arch: arm: mach-k3: Delete tifs node in DT fixup
Delete tifs DT node as part of fixup.
TISCI API reported msmc_size, does not include 64KB reserved size for
tifs aka MSMC comms memory, see documentation[0].
As part of fixup, original code uses TISCI API reported msmc_size as
size for SRAM DT node.
tifs node is similar to l3-cache, which should hold address above
msmc_size, and should be deleted before passing control to OS.
