coresight: etm4x: Fix save and restore of TRCVMIDCCTLR1 register
In commit f188b5e76aae ("coresight: etm4x: Save/restore state across CPU low power states"), mistakenly TRCVMIDCCTLR1 register value was saved in trcvmidcctlr0 state variable which is used to store TRCVMIDCCTLR0 register value in etm4x_cpu_save() and then same value is written back to both TRCVMIDCCTLR0 and TRCVMIDCCTLR1 in etm4x_cpu_restore(). There is already a trcvmidcctlr1 state variable available for TRCVMIDCCTLR1, so use it.
