ARM: 8342/1: VDSO: depend on CPU_V7
When targeting ARMv3 (e.g. rpc) and enabling CONFIG_VDSO we get:
arch/arm/vdso/datapage.S:13: Error: selected processor does not
support ARM mode `bx lr'
One fix considered was to use 'ldr pc,lr' for such configurations, but
since the VDSO is unlikely to be useful for pre-v7 hardware, just make
it depend on CONFIG_CPU_V7.
