1. Implement the following vgpu functions to support clk-arb:
- vgpu_clk_get_range() to return min and max freqs from
supported frequencies
- implement vgpu_clk_get_round_rate() which sets rounded
rate to input rate. Rounding is handled in RM Server
- modify vgpu_clk_get_freqs() to retrieve freq table in IVM
memory instead of copying the value in array as part of cmd
message.
2. Add support for clk-arb related HALs for vgpu.
3. support_clk_freq_controller is assigned true for vgpu
provided guest VM has the privilege to set clock frequency.

- This patch enables HWPM Mode-E context switch for gv11b.
- Write new pm mode to context buffer header. Ucode use
this mode to enable mode-e context switch. This is Mode-B
context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.
- For Mode-E ctxsw it is required that engine_sel
is set to 0xFFFFFFFF.
- Default 0 is a valid signal and causes problems.

2) "HSM ERROR 42, GPU" from SCE if it detects that an interrupt is

Fix these by masking all interrupts just before gpu power off

While masking interrupts, if there are any pending interrupts,
