[PATCH] tty: serial: fsl_lpuart: fix the wrong mapbase value

[Sherry Sun <sherry.sun@nxp.com>]

From: Andy Duan <fugang.duan@nxp.com>

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.
