[PATCH 13/18] arm: mach-k3: am62p: annotate switch/case fallthrough

[Andre Przywara]

The MMC boot mode selection for the TI AM62P series of SoCs uses an
implicit switch/case fallthrough for falling back to some default
boot mode.

Add our "fallthrough;" statement-like macro before the default branch in
the code, to avoid a warning when GCC's -Wimplicit-fallthrough warning
option is enabled.
