[WHAT & HOW]
Integer multiplies integer may overflow in context that expects an
expression of unsigned/siged long long (64 bits). This can be fixed
by casting integer to unsigned/siged long long to force 64 bits results.
This fixes 26 OVERFLOW_BEFORE_WIDEN issues reported by Coverity.

[why]
OPP input rect aka odm slice rect is a hardware dependent parameter that
can't be determined by SPL software logic. Therefore we need to
explicitly pass odm slice rect in. So ODM slice rect calculation is
moved out of SPL.
[how]
add odm_slice_rect parameter in spl_in

[why]
When optc uses two pixel per container, each ODM slice width must be an
even number.
[how]
If ODM slice width is odd number increase it by 1.

[Why]
Enable sharpener support for DCN401
[How]
- Removed memcmp check that was preventing ISHARP from being enabled.
- Add missing ISHARP register defines, masks, and writes.
- Add programming of Blur and Scale coefficients.
- Program FMT_MODE and NLDELTA registers based on LLS_PREF and pixel
- format
- Only enable ISHARP for YUV420
- Add disabling of ISHARP
- Add debug flags and registry keys for debugging ISHARP.
- Set default to medium level

[Why]
Enable adaptive scaler support for DCN401
[How]
- Enable build flag for SPL
- Set prefer_easf flag to true
- Apply light linear scaling policy based on transfer function and pixel
format. Choose between linear or non-linear scaling
- Set matrix_mode based on pixel format
- Disable ring estimator
- Add missing EASF register defines, masks, and writes
- Disable EASF if scale ratio or number of taps is unsupported and when
bypassing the scaler
- Add debug flags and registry keys for debugging SPL and EASF
- Add support for Visual Confirm with EASF
