arm: armv7-a: Compile and tune for armv7-a instead of armv5
arch/arm/Makefile references armv5 for backwards compatibility with
older compilers. This patch removes those references to armv5,
since by now newer compilers are required which should have armv7
support enabled.
The Makefile also also has a list of options for mtune, but the
entry for CONFIG_CPU_V7A is empty, so this patch tunes the
CPU_V7A architecture to generic-armv7-a.
The following size changed apply to omap3_logic using GCC.
