hwrng: nomadik - add ARM_AMBA dependency

[ Upstream commit efaa2d815a0e4d1c06750e587100f6f7f4ee5497 ]

Compile-testing this driver is only possible when the AMBA bus driver is
available in the kernel:

x86_64-linux-ld: drivers/char/hw_random/nomadik-rng.o: in function `nmk_rng_remove':
nomadik-rng.c:(.text+0x67): undefined reference to `amba_release_regions'
x86_64-linux-ld: drivers/char/hw_random/nomadik-rng.o: in function `nmk_rng_probe':
nomadik-rng.c:(.text+0xee): undefined reference to `amba_request_regions'
x86_64-linux-ld: nomadik-rng.c:(.text+0x18d): undefined reference to `amba_release_regions'

The was previously implied by the 'depends on ARCH_NOMADIK', but needs to be
specified for the COMPILE_TEST case.
