tty: serial: fsl_lpuart: fix the wrong mapbase value
[ Upstream commit d5c38948448abc2bb6b36dbf85a554bf4748885e ]
Register offset needs to be applied on mapbase also.
dma_tx/rx_request use the physical address of UARTDATA.
Register offset is currently only applied to membase (the
corresponding virtual addr) but not on mapbase.
Fixes: 24b1e5f0e83c ("tty: serial: lpuart: add imx7ulp support")
