The MFD-specific header will go away because it duplicates defines from
exynos-regs-pmu.h.

The newly added exynos lpass driver produces a build warning when
CONFIG_PM is disabled since the only callers of exynos_lpass_disable
are under an #ifdef:
drivers/mfd/exynos-lpass.c:93:13: error: 'exynos_lpass_disable' defined but not used [-Werror=unused-function]
static void exynos_lpass_disable(struct exynos_lpass *lpass)
This removes the #ifdef and replaces it with __maybe_unused annotations
so the compiler can leave out the unused code silently with less
room for mistakes.

This patch adds common driver for the Top block of the Samsung Exynos
SoC Low Power Audio Subsystem. This is a minimal driver which prepares
resources for IP blocks like I2S, audio DMA and UART and exposes
a regmap for the Top block registers. Also system power ops are added
to ensure the Audio Subsystem is operational after system suspend/resume
cycle.
