2021-03-23drm/amd/display: Correct algorithm for reversed gammaCalvin Hou

2021-03-23drm/amd/display: Add changes for dsc bpp in 16ths and unify bw calculationsDillon Varone
[Why?] Some code still expected bpp to be used in whole bits, not 16ths. dsc.c uses redundant function now found in dc to calculate stream bandwidth from timing. [How?] Fix code to work with 16ths instead of whole bits for dsc bpp. Refactor get_dsc_bandwidth to accept inputs in 16ths of a bit. Use dc function to calculate bandwidth from timing, and make dsc bw calculation a part of dsc.c.

gfx_v8_0_parse_sq_irq() is using in_task() to distinguish if it is invoked from a workqueue worker or directly from the interrupt handler. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. gfx_v8_0_parse_sq_irq() is invoked directly either from a worker or from the interrupt service routine.
