[PATCH v2 0/2] clk: aspeed: Expose RMII RCLK gate for MACs 1-2 on AST2500

This series is two small changes enable kernel support for controlling the RMII
RCLK gate on AST2500-based systems. Previously the kernel has assumed u-boot
has ungated RCLK for networking to function.

RMII is commonly used for NCSI, which itself is commonly used for BMC-based
designs to reduce cabling requirements for the platform.

* Rename macros and clock names based on Joel's feedback.

Please review!
