serial: lpuart: restructure lpuart driver
Drop CONFIG_LPUART_32B_REG. Move the register structure to a common file include/fsl_lpuart.h Define lpuart_serial_platdata structure which includes the reg base and flags. For 32Bit register access, use lpuart_read32/lpuart_write32 which handles big/little endian. For 8Bit register access, still use the orignal code.
