tty: serial: cpm_uart - fix init when SMC is relocated
[ Upstream commit 06aaa3d066db87e8478522d910285141d44b1e58 ]
SMC relocation can also be activated earlier by the bootloader,
so the driver's behaviour cannot rely on selected kernel config.
When the SMC is relocated, CPM_CR_INIT_TRX cannot be used.
But the only thing CPM_CR_INIT_TRX does is to clear the
rstate and tstate registers, so this can be done manually,
even when SMC is not relocated.
