Since upgrading to gcc9, warnings are issued:
"taking address of packed member of ‘...’ may result in an unaligned
pointer value"
Fix this by converting two functions to use unaligned access since packed
structures may be on an unaligned address, depending on USB hardware.

Applied both, thanks.
With these two patches applied to origin/master GCC 9.2.1 does not
produce warnings anymore but for tbs2910_defconfig:
u-boot.imx exceeds file size limit:
limit: 0x5fc00 bytes
actual: 0x60c00 bytes
excess: 0x1000 bytes
make: *** [Makefile:1159: u-boot.imx] Error 1
make: *** Deleting file 'u-boot.imx'
So irrespective of my patches for the USB keyboard we need to address
the size limit on TBS2910.
Is that due to my cleanup patches? Can you compare the size by compiling
without them? That should work if you leave away the -Werror switch.

GCC 9.2.1 without your patches but with -Wno-address-of-packed-member:
u-boot.imx exceeds file size limit:
limit: 0x5fc00 bytes
actual: 0x60c00 bytes
excess: 0x1000 bytes
