[ Upstream commit 33239152305567b3e9bf052f71fd4baecd626341 ]
Clock plan for Ralink SoC RT3883 needs an extra 'periph' clock to properly set some peripherals that has this clock as their parent. When this driver was mainlined we could not find any active users of this SoC so we cannot perform any real tests for it. Now, one user of a Belkin f9k1109 version 1 device which uses this SoC appear and reported some issues in openWRT: - https://github.com/openwrt/openwrt/issues/16054 The peripherals that are wrong are 'uart', 'i2c', 'i2s' and 'uartlite' which has a not defined 'periph' clock as parent. Hence, introduce it to have a properly working clock plan for this SoC.
