gate->enable_refcnt is within clk-periph-gate which gets updated when 
enable/disable callbacks get execute thru clk_core_enable/disable.
But actual enable_count used in clk_gate_restore_context is the one 
which gets updated with in the clk core enable/disable functions which 
invokes these callbacks. Depending on this enable_count in clk core it 
invokes enable/disable.

So, this will cause mismatch if we handle refcnt during save/restore of 
tegra_clk_periph_gate_ops and also enable/disable thru this 
clk_gate_restore_context is based on enable_count from clk core.

Also, to align both CLK & RST to the exact state of register, doing 
save/restore in tegra_clk_periph_gate_ops and invoking this after source 
restore for peripheral clock, seems cleaner to avoid any 
misconfiguration b/w rst & clk settings.
