sc7180: Remove QcLib specific changes from CB UART

To achieve 115200 baudrate QcLib reconfigures UART frequency
with the lowest supported frequency from QUP clock table.
With this console logs were getting corrupted at qclib stage.

In ChromeOS coreboot, baudrate is configuarable using Kconfig.
QcLib should not assume the baudrate and reconfigure any UART
register once after the configuration is done in coreboot.

To fix the issue QcLib was changed to not to reconfigure
any UART registers. Hence clock_configure_qup() is not required
in coreboot UART driver.
