In usb_musb_pm_init, we attempt to access an MUSB register
when the i-clock may not be on, or the module is otherwise
not accessible.
We need to either:
- enable the clock before this access, or
- remove this code and move it to the bootloader, or
- enable the clock in the bootloader
If we enable the clock in the bootloader, we might as well
add the workaround in the bootloader itself. This code will
anyway be changed once hwmod is in place, so remove it for now
This allows us to boot the kernel on certain OMAP3 boards with
a bootloader that doesn't enable this clock. Without this, we
will need to upgrade the bootloaders on these boards.
