Both MSM8916 and MSM8939 have unnecessarily large reservations for the
venus firmware for some reason. According to the ELF headers and
downstream [1] 5 MiB is enough. Let's set the minimum size as default.

With the dynamic reserved memory allocations boards can easily override
this if needed, although in practice there does not seem to be any
device with a different venus firmware size.

[1]: https://git.codelinaro.org/clo/la/kernel/msm-3.10/-/blame/LA.BR.1.2.9.1-02310-8x16.0/arch/arm/boot/dts/qcom/msm8939-common.dtsi#L69Signed-off-by: Stephan Gerhold <stephan@gerhold.net>

The modem firmware size is typically highly device-specific.
The current size of the mpss_mem region in msm8916.dtsi (0x2b00000)
only works for some APQ8016 devices without full-featured modem,
such as the DragonBoard 410c.

The full modem firmware is typically about twice as large (~45 MiB
-> ~90 MiB) but also varies by a few MiB from device to device. Since
these devices are quite memory-constrained nowadays it's important to
minimize the unnecessary memory reservations.

Make it clear that each board needs to specify the necessary mpss_mem
size by replacing the DB410c-specific size in msm8916.dtsi with a
simple comment. &mpss_mem is disabled by default so it's fine to leave
some properties up to the boards if they want to enable it.

Now that we no longer have fixed addresses for the firmware memory
regions, disable them by default and only enable them together with

This frees up unnecessary reserved memory for boards that do not use

the next step.

At a first glance the MBA memory region on MSM8916 looks intentionally
placed at the fixed address 0x8ea00000. This is what the ELF headers of
the firmware specify as base address, and the typical Qualcomm-specific
bits suggest the binary is not relocatable.

However, on a closer look this is pointless: Unlike other firmware
images the hardware expects to have the raw ELF image loaded to the MBA
region, including the ELF header (without parsing it at all). This
means that we actually just load the ELF header (not the code!) at
0x8ea00000. The real LOAD segments follow at arbitrary aligned
addresses depending on the structure of the ELF binary.

In practice it looks like we can use an arbitrary 1 MiB-aligned region
for MBA. The downstream/vendor kernel just allocates this dynamically
at an arbitrary (aligned) address.

Drop the pointless fixed address and use the new dynamic reserved
memory mechanism to allocate a region close to the others. This reduces
gaps in the memory map and provides Linux with more contiguous memory.

Most of the reserved firmware memory on MSM8916 can be relocated when
respecting the required alignment. To avoid having to precompute the
reserved memory regions in every board DT, describe the actual
requirements (size, alignment, alloc-ranges) using the dynamic reserved
memory allocation.

This approach has several advantages:

 1. We can define "templates" for the reserved memory regions in
    msm8916.dtsi and keep only device-specific details in the board DT.
    This is useful for the "mpss" region size for example, which varies
    from device to device. It is no longer necessary to redefine all
    firmware regions to shift their addresses.

 2. When some of the functionality (e.g. WCNSS, Modem, Venus) is not
    enabled or needed for a device, the reserved memory can stay
    disabled, freeing up the unused reservation for Linux.

 3. Devices with special requirements for one of the firmware regions
    are handled automatically. For example, msm8916-longcheer-l8150
    has non-relocatable "wcnss" firmware that must be loaded exactly
    at address 0x8b600000. When this is defined as a static region,
    the other dynamic allocations automatically adjust to a different
    place with suitable alignment.

All in all this approach significantly reduces the boilerplate necessary
to define the different firmware regions, and makes it easier to enable
functionality on the different devices.
