[PATCH 01/15] thermal/drivers/samsung: Select REGMAP_MMIO for EXYNOS_ACPM_THERMAL

[Tudor Ambarus]

The Exynos ACPM TMU driver calls devm_regmap_init_mmio() in
acpm_tmu_probe(), which requires CONFIG_REGMAP_MMIO.

When ARCH_EXYNOS is enabled, REGMAP_MMIO is selected transitively via
EXYNOS_PMU. However, both the Samsung thermal menu and
EXYNOS_ACPM_PROTOCOL allow COMPILE_TEST builds with ARCH_EXYNOS disabled
(COMPILE_TEST && !ARCH_EXYNOS), where nothing in EXYNOS_ACPM_THERMAL's
dependency chain selects REGMAP_MMIO, resulting in build failures when
REGMAP_MMIO is not enabled by another driver.

Select REGMAP_MMIO under config EXYNOS_ACPM_THERMAL.
