arm64: dts: amlogic: g12: assign the MMC B and C signal clocks
[ Upstream commit be2ff5fdb0e83e32d4ec4e68a69875cec0d14621 ]
The amlogic MMC driver operate with the assumption that MMC clock
is configured to provide 24MHz. It uses this path for low
rates such as 400kHz.
Assign the clocks to make sure they are properly configured
