Commit b91d935feebdf2c3edef19949023645b6cb34b20
("Add CFI debug frame information for ASM functions") modifies the
assembly macros 'func' and 'endfunc' to include CFI debug frame
information.
The rockchip platform uses a custom version of the 'func' macro with the
common 'endfunc' macro. The custom macro wasn't updated in
b91d935feebdf2c3edef19949023645b6cb34b20 resulting in the following
build error:
plat/rockchip/rk3399/drivers/pmu/plat_pmu_macros.S: Assembler messages:
plat/rockchip/rk3399/drivers/pmu/plat_pmu_macros.S:155: Error: .cfi_endproc without corresponding .cfi_startproc
Makefile:532: recipe for target 'build/rk3399/release/bl31/plat_helpers.o' failed
make: *** [build/rk3399/release/bl31/plat_helpers.o] Error 1
Fixing this by updating the sram_func macro in the rk3399 port.

This allows the debugger to print the callstack when there is an
assembly function in the callstack.
It will work as long as the CFA pointer (frame pointer) location is not
modified (i.e. x29 is not touched in AArch64 state). It is the case in
almost all assembly functions, so this patch improves the average
debugging experience. Call stacks from the debugger should still be
interpreted with care. In more complex functions, one could use .cfi*
directives to inform the debugger about the new location of the CFA
pointer.
