mb/purism/librem_cnl: Remove unneeded explicit PNP enable for UART

Remove explicit PNP 6e.1 configuration for UART.  This had no effect,
the SuperIO is actually on I/O port 2e.  Enabling the 8250IO driver is
sufficient to use the UART, the UART device is enabled by default.

Test: Build Mini v2 with and without CONFIG_ENABLE_EC_UART1, boot and
check output on serial.
