Even the BCM number is inconsistent here.

I may have missed that discussion. My point was about consistency with
existing ARCH_* definitions in the arm64 Kconfig.platforms. I can see
why it's easier for you since some drivers are built based on
ARCH_BCM2835. Looking at drivers/clk/bcm/Makefile, there is an
inconsistent mix of CLK_BCM_* and ARCH_BCM_*. I would rather have a new
CLK_BCM2835 that's selected/enabled accordingly (maybe simply depending
