[PATCH v1] ARM: debug: fix broken DEBUG_LL_INCLUDE for multi platform

[Srinivas Kandagatla]

On multi_v7_defconfig using def_bool in Kconfig can override the selection
made as part of DEBUG_LL. This is because def_bool will set the config to true
if the expression evaluates to true, which is what was happening in
multi_v7_defconfig. ARCH_SPEAR13XX selects DEBUG_UART_PL01X overriding any
previous DEBUG_LL selections and resulting in DEBUG_LL_INCLUDE to
always point to debug/pl01x.S.

Choice menu already provides options for selecting pl01x and 8250 via
DEBUG_LL_UART_PL01X and DEBUG_LL_UART_8250 options. so I don't see point of
having dependencies or def_bool options for PL01X and 8250.
Other than getting them selected automatically and overriding
DEBUG_LL selections.

Without this patch its impossible to get earlyprintk working with multi_v7_defconfig

Am resending this patch as I missed arm-soc people in the loop.
