Using ulong is wrong as its size depends on the Host CPU architecture
(32-bit vs. 64-bit) although the Cortex-M4 is always 32-bit.

Without this patch, the stack and PC are obviously wrong and it
generates an abort when used on 64-bit processors such as the i.MX8MQ.

To add support for power sink when booting in dead battery, we

Some power delivery source send the source capability by 2 stages:
1st stage send the source capability message with only basic 5V
PDO, after the 5V power session setup, 2nd stage it will send full
source capabilities with all PDOs it can support, in this case, we
should go on to process the following PD source cap to have a new

This patch is important as currently Linux is not initializing the
USB clocks correctly, so if we don't do it u-boot USB host mode
does not work.  This is a temporary fix until the Linux kernel is
patched to work properly.

Regardless we want USB working properly for booting and recovering
our board, although this needs to be converted to a DM driver model.
