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.

Do not force GM20b GPCPLL post divider to 1:2 settings before switching
to bypass clock if PLL output frequency is increased as a result. Move
this step under bypass. However, this step is still needed in case when
PLL can be configured without switch to bypass.

The code took reference to gk20a by using gk20a_busy_noresume(). This
function takes pm runtime reference only to the GPU, however, the code
dropped the reference by calling gk20a_idle() which also drops the
reference to the platform dependencies (host1x).
This patch modifies gm20b_mm_mmu_vpr_info_fetch_wait() to drop only
the GPU reference.

- No longer bypass PLL for re-locking if it is already enabled, and
post divider as well as feedback divider are changing (input divider
change is still under bypass only).
- Use post divider instead of external linear divider to introduce
