mfd: vexpress: Add !ARCH_USES_GETTIMEOFFSET dependency
The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn
conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig
warning when it is set:
warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET)
This was apparently hidden by the fact that no ARM platform that
still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we
already have a dependency on GPIOLIB that I added a while ago.
However, after 296ad4acb8ef ("gpio: remove deps on
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable
CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG
as well.
This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET
to guarantee that we can enable the CLKSRC_MMIO driver without
getting warnings.
