Moved detection of idempotent GPCPLL operations from set_pll_freq()
function to its callers, e.g., explicitly check when enable operation
is called on already enabled PLL, instead of passing same frequency
to set_pll_freq() in such case. Similarly explicitly check when disable
operation is called on already disabled PLL.
Also moved check for GPU powered on from set_pll_freq() to callers,
and skip call to set interface if not.
Added last GPCPLL configuration structure updated after successful
completion of set_pll_freq() function.

Used GPU device name in clock get operation (instead of fixed name),
to make operation is common for GK20A and GM20B. Updated clock ids
in tegra clock framework accordingly.

Made GK20A and GM20B clock operations static, since they are invoked
only via HAL interfaces.
