[PATCH 2/5] serial: apbuart: remove check for zero baud rate from uart_get_baud_rate()

[Hugo Villeneuve]

From: Hugo Villeneuve <hvilleneuve@xxxxxxxxxxxx>

The minimum baud rate supported by this driver is 0, so even for the B0
case, uart_get_baud_rate() will return 9600, not zero. This check predates
commit 16ae2a877bf4 ("serial: Fix crash if the minimum rate of the device
is > 9600 baud") and is no longer necessary so remove it.
