ARM: 9314/1: tcm: move tcm_init() prototype to asm/tcm.h
The function definition is in a file that does not include the
header with the declaration:
arch/arm/kernel/tcm.c:256:13: error: no previous prototype for 'tcm_init'
Move the declaration to a global header where it can actually be
included.
Fixes: de40614e92bf ("ARM: 7694/1: ARM, TCM: initialize TCM in paging_init(), instead of setup_arch()")
