The HB onboard audio currently makes use of the imx-audio-sgtl5000
binding. This binding does not support auxiliary audio devices such
as external amplifiers. The simple-audio-card binding does support
this property which allows systems incorporating the HB to add an
auxiliary device that's attached to the HB audio jack with an
overlay. Convert the HB onboard audio to use simple-audio-card for
this additional flexibility.

Pass the memory unit-adress to fix the following build warnings with W=1:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
There are cases where dts passes an empty memory node, which will be filled
by the bootloader. Passing the memory base address still allows the
bootloader to fill the memory size.

PCIe reset signals are active low, and our GPIO for this is directly
connected to the PCIe reset. However, as the PCIe driver was not using
the flag, the specification of '0' flags (which means active high) had
not been noticed. Correct this oversight, and switch to using the
GPIO flag definitions instead.

pwm1: In case HummingBoard base carrier; this pin drives through a serial
capacitor the mono out of the audio jack.
In case HummingBoard pro the this pad can be reached by wiring to
C8 capacitors on the board.
pwm2: Setup pwm2 on gpio-1 but leave the default function of the iopad as
a gpio.
The user can change the io pad mux in user space and therefore use
this function on gpio-1 (pin number 7 on the 26 pin header).
