The driver's probe() method is written as if platform_get_irq() returns 0
on error, while actually it returns a negative error code (with all the
other values considered valid IRQs).  Rewrite the driver's IRQ checking
code to pass the positive IRQ #s to ata_host_activate(), propagate errors
upstream, and treat IRQ0 as error, returning -EINVAL, as the libata code
treats 0  as  an indication that polling should be used anyway...

The return value of ata_qc_from_tag() is checked in the whole
kernel except for two calls in sata_dwc_isr(), which may lead
to null-pointer-dereference. Add return value checks to avoid
such case.

SATA controller used in Xilinx ZynqMP platform uses xilinx GT phy
which has 4 GT lanes and can be used by 4 peripherals at a time.
SATA controller uses 1 GT phy lane among the 4 GT lanes. To configure
the GT lane for the SATA controller, the below sequence is expected.

1. Assert the SATA controller reset.
2. Configure the xilinx GT phy lane for SATA controller (phy_init).
3. De-assert the SATA controller reset.
4. Wait for PLL of the GT lane used by SATA to be locked (phy_power_on).

The ahci_platform_enable_resources() by default does the phy_init()
and phy_power_on() but the default sequence doesn't work with Xilinx
platforms. Because of this reason, updated the driver to support the
new sequence.

Added cevapriv->rst check, for backward compatibility with the older
sequence. If the reset controller is not available, then the SATA
controller will configure with the older sequences.

This patch updates the documentation for the CEVA controller for adding
the optional properties for 'phys' and 'resets'.
