[PATCH] spi: qup: Depend on ARM && COMPILE_TEST to avoid build error

[Axel Lin <axel.lin-8E1dMatC8ynQT0dZR+AlfA@public.gmane.org>]

This driver uses writel_relaxed() which does not exist in x86, ppc, etc.
Make it depend on ARM && COMPILE_TEST to avoid below build error:

  CC [M]  drivers/spi/spi-qup.o
drivers/spi/spi-qup.c: In function 'spi_qup_set_state':
drivers/spi/spi-qup.c:180:3: error: implicit declaration of function 'writel_relaxed' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [drivers/spi/spi-qup.o] Error 1
make[1]: *** [drivers/spi] Error 2
make: *** [drivers] Error 2
