A bunch of ID_AA64MMFR0_TGRAN_* constant definitions appear twice
in arch/arm64/include/asm/sysreg.h, so drop the duplicates.

Whoops. Looks like these were added in commit:
4bf8b96ed3f7e114 ("arm64: Check for selected granule support")
... and then duplicated along with all the other registers in commit:
3c739b5710843621 ("arm64: Keep track of CPU feature registers")
This patch looks sound to me, so:

Thanks for tracking that down, I was worried we might have messed up a
merge conflict and potentially broken something else at the same time.
