Subject: [PATCH] mfd: intel_soc_pmic: allow COMPILE_TEST or I2C_DESIGNWARE_PLATFORM

Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC,
for Crystal Cove) be built on an "allmodconfig" build, when
I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage.

The PMIC driver won't work in this case since it requires
I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding
"|| COMPILE_TEST" does improve the build test coverage.
