mtd: hyperbus: HBMC_AM654 should depend on ARCH_K3

The AM65x HyperBus controller is only present on Texas Instruments AM65x
SoCs.  Hence add a dependency on ARCH_K3, to prevent asking the user
about this driver when configuring a kernel without support for the
Texas Instruments Inc. K3 multicore SoC architecture.
