This extends the peripherals supported by the imx7d-pico.dtsi. It
adds:

 - I2C2
 - Flexcan (flexcan1 and flexcan2 ports)
 - USDHC1
 - UART (6 and 7 ports)
 - PWM (4 ports)
 - eCSPI3

i.MX fixes for 4.20, round 3:
 - A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct
   the description of the Wifi clock.
 - Change SW2ISO count to get a safer ARM LDO ramp-up time, so that
   different boards can be covered. This fixes the ARM LDO failure seen
   on some customer boards.

TPA6130A2 SD pin on RDU1 is not really controlled by SoC and instead
is only meant to notify the system that audio was "muted" by external
actors. To accommodate that, drop "power-gpio" property of hpa1 node as
well as specify a name for that GPIO so that userspace can access it.

i.MX7S contains a single Cortex-A7, hence the second interrupt specifier
cell for Private Peripheral Interrupts should use "GIC_CPU_MASK_SIMPLE(1)".
