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.

Boards based on imx6qdl have duplicate memory nodes:

- One coming from the imx6qdl.dtsi file.

Fix the duplication by removing the memory node from
the imx6qdl.dtsi file and by adding 'device_type = "memory";'
in the board Device Tree.

number of CPU cores the interrupt controller is wired to.

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

Likewise, i.MX7D contains two Cortex-A7 cores, so it should use
