gpu: nvgpu: prepare MCLK/GPCLK enumeration change

GPC2CLK has been replaced with GPCCLK on user API.
Remove related definition from kernel API.
GPCLCK and MCLK are currently assigned EQU values in kernel API.
We want to move to a simple enumeration as used in nvrm_gpu.
During the transition, an alias value will be defined for each
clock, and kernel will accept both.
