Debarshi Dutta eaab8ad1f2 gpu: nvgpu: move some fifo based HAL ops to hal.channel unit
a) free_channel_ctx_header is used to free the channel's underlying subctx
and belongs to the hal.channel unit instead of fifo. Moved the same and
renamed the HAL ops to free_ctx_header. The function
gv11b_free_subctx_header is moved to channel_gv11b.* files and also
renamed to gv11b_channel_free_subctx_header.

b) ch_abort_clean_up is moved to hal.channel unit

c) channel_resume and channel_suspend are used to resume and suspend all
the serviceable channels. This belongs to hal.channel unit and are
moved from the hal.fifo unit.

The HAL ops channel_resume and channel_suspend are renamed to
resume_all_serviceable_ch and suspend_all_serviceable_ch respectively.

gk20a_channel_resume and gk20a_channel_suspend are also renamed to
nvgpu_channel_resume_all_serviceable_ch and
nvgpu_channel_suspend_all_serviceable_ch respectively.

d) set_error_notifier HAL ops belongs to hal.channel and is moved
accordingly.
