1d7592f84f reset: simple: Enable for ASPEED systems
ASPEED BMC SoCs have a reset controller in the LPC IP that can be
controlled using this driver to release the UARTs from reset.

No special configuration is required, so only the compatible string is
added.

81c22ad0cc reset: add reset-simple to unify socfpga, stm32, sunxi, and zx2967
Copy reusable parts from the sunxi driver, to add a driver for simple
reset controllers with reset lines that can be controlled by toggling
bits in exclusive, contiguous register ranges using read-modify-write
cycles under a spinlock.

The following patches will replace compatible reset drivers with
reset-simple, extending it where necessary.
