reset: ast2500: Use SCU for reset control
The System Control Unit (SCU) controller of Aspeed
SoCs provides the reset control for each peripheral.
This patch refactors the reset method to leverage
the SCU reset control. Thus the driver dependency
on watchdog including dedicated WDT API and reset
flag encoding can be eliminated.
The Kconfig description is also updated accordingly.

- Support for reset controller on AST2500 SoC. This controller uses
- watchdog to reset different peripherals and thus only supports
- resets that are supported by watchdog. The main limitation though
- is that some reset signals, like I2C or MISC reset multiple devices.
