There are 4 Filter coefficient tables available. The table to be
loaded in the IP is determined by the scaling ratio
Scale Up: Always use 6tap
Scale Dn: Different table selected based on scaling ration

Coefficient register base address offset changed in IP from 0x400 to
0x800 to accomodate all supported taps.
Split Phase and Coefficient programming logic in 2 independent
API's. For Bicubic and Bilinear scalers only Phase needs to be
programmed.

4 Samples/Clock phase calculation logic works on 64bit entities.
However a 32bit variable was used that caused wrong phase
information to be generated. Updated relevant variables to 64b

- IP updated to add multiple pixel/clk support.
- Added default filter coefficient table for 6/8/10/12 taps
- Added API to load default coefficients or allow user to load
externally defined coefficients
- Peformed code cleanup to remove coefficient generation logic
(scaler to use fixed coefficients)
