Add Reset Driver for ast2500 SoC. This driver uses Watchdog Timer to perform resets and thus depends on it. The actual Watchdog device used needs to be configured in Device Tree using "aspeed,wdt" property, which must be WDT phandle, for example:
rst: reset-controller { compatible = "aspeed,ast2500-reset"; aspeed,wdt = <&wdt1>; }

Changes in v1:
- Remove unnecessary check for error in dev_get_priv
- Fix comment
- Rename wdt_reset call to wdt_expire_now
