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. Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

This enables a simple reset controller driver for reset lines that
that can be asserted and deasserted by toggling bits in a contiguous,
exclusive register space.
- Currently this driver supports Altera SoCFPGAs, the RCC reset
- controller in STM32 MCUs, Allwinner SoCs, and ZTE's zx2967 family.
