clocksource/drivers/timer-imx-tpm: Specify clock name for timer-of
i.MX TPM needs "ipg" clock for register access and "per" clock for timer function, the driver gets "ipg" clock by searching the clock name, but timer-of initialization will get first clock in device tree TPM node since no clock name specified in of_clk, that means the "per" clock MUST be the first clock entry in device tree TPM node, this patch specifies clock name for of_clk to avoid this restriction, it makes TPM driver work properly with different sequence of clock entries in device tree TPM node.
