serial: qcom-geni: fix UART_RX_PAR_EN bit position
UART_RX_PAR_EN is incorrectly defined as bit 3, which triggers false
framing errors (S_GP_IRQ_1_EN) and causes received data to be dropped
when parity is enabled and the parity bit is 0.
Define UART_RX_PAR_EN as bit 4 of the SE_UART_RX_TRANS_CFG register, as
specified in the reference manual.
