[PATCH] backlight: fix build error when CONFIG_ARCH_OMAP1_ANY=n

[Yu Liao <liaoyu15@huawei.com>]

If CONFIG_BACKLIGHT_OMAP1=y and CONFIG_ARCH_OMAP1_ANY=n, it leads a build
error:

	drivers/video/backlight/omap1_bl.o: In function `omapbl_probe':
	omap1_bl.c:(.text+0x198): undefined reference to `omap_cfg_reg'

Here is the link to the issue reported by kernel test bot:

https://lore.kernel.org/lkml/202211060819.fHDGmrB4-lkp@intel.com/

arch/arm/mach-omap1/mux.c where defines omap_cfg_reg() depends on
CONFIG_ARCH_OMAP1_ANY, so make CONFIG_BACKLIGHT_OMAP1 depends on
CONFIG_ARCH_OMAP1_ANY to fix it. ARCH_OMAP1_ANY depends on ARCH_OMAP1,
so the following logic is equivalent:

ARCH_OMAP1_ANY && (ARCH_OMAP1 || COMPILE_TEST) = ARCH_OMAP1_ANY
