spi: aspeed: Add support for the AST2700 SPI controller
Extend the driver to support the AST2700 SPI controller. Compared to
AST2600, AST2700 has the following characteristics:
- A 64-bit memory address space.
- A 64KB address decoding unit.
- Segment registers now use (start <= range < end) semantics,
which differs slightly from (start <= range <= end) in AST2600.
- Known issues related to address decoding range registers have been
resolved, and the decoding range is now 1GB, which is sufficient.
Therefore, the adjust_window callback is no longer required on AST2700
for range adjustment and bug fixes.
- The SPI clock divider method and timing calibration logic remain
unchanged from AST2600.
