[PATCH] serial: efm32: Fix parity management in 'efm32_uart_console_get_options()'

[Christophe JAILLET]

UARTn_FRAME_PARITY_ODD is 0x0300
UARTn_FRAME_PARITY_EVEN is 0x0200
So if the UART is configured for EVEN parity, it would be reported as ODD.
Fix it by testing if the 2 bits are set in the ODD case.
