The flash clock frequency may have been set to a different value by a
bootloader. Set the frequency according to the configured value. Use a
table of pre-calculated dividers to get the closest value for the flash
frequency, achieving for MIMXRT10xx:
30 -> 30.85 MHz
50 -> 49.65 MHz
60 -> 60 MHz
75 -> 75.13 MHz
80 -> 80 MHz
100 -> 99.31 Mhz
133 -> 132.92 MHz
166 -> 166.15 MHz
for MIMXRT1176:
30 -> 31 MHz
50 -> 52.8 MJz
60 -> 58.7 MHz
75 -> 75.4 MHz
80 -> 75.4 MHz
100 -> 105.6 MHz
133 -> 132 MHz
166 -> 176 MHz

Changes:
- Change the LUT table ordering to be similar to the order of the
UF2-Bootloader and fsl_romapi.h.
- Rewrite the LUT entry for PAGEPROGRAM_QUAD and update the LUT. That
enabled QUAD program again.

Separate low level flash access from mimxrt flash driver object. Allows
better abstraction from hardware for testing and reuse in other areas (e.g.
bootloader).
