Allocate space at runtime for PMU sequences, this helps to reduce the size
of nvgpu_pmu struct when LS_PMU support is not required.
Allocation happens at pmu early init stage & will deinit at remove_support
stage.
And also removed some unused seq functions as part of CL

MISRA rule 2.2 defines dead code as "operations which are executed but
removal of these operations has no effect on program behavior".
Variable initializations violate this rule if initialized value is not
used and replaced.
This patch fixes some of these reported violations.

Created PMU fw unit to hold PMU RTOS f/w specific ops, images,
flags & command arguments needed for PMU RTOS ucode support.
Moved PMU fw ops from gk20a.gpu_ops to pmu.fw.ops as these ops
are needed to support different version of PMU fw version for
different chips

This patch fixes below two issues.
1.Currently clk arb exit is called after GPU registers are released.
This causes crash when clk arb WQ accesses GPU HW register for status.
The ideal way is to exit the clk_arb which removes the WQ from running
before calling lockout register.
2.Check if dGPU is dying during processing of PMU Commands.
This prevents race condition when PMU is waiting for response and device
is shutdown.
