This series addresses some weaknesses in the current UART pinmuxing
mainly observable when trying to use a different UART instance as main
U-Boot serial console.

Add pinmuxing comment stating that TRISTATE means the output driver is
tri-stated and INPUT means the input driver is enabled vs. OUTPUT where
it is disabled.

Fix SPI1 and UART2/3 resp. UARTB/C pinmuxing.
Note: The former was illegally muxing multiple SoC balls onto the same
internal SoC signal which caused rather strange behaviour regarding
the RS232 serial transceiver ForceOFF# pins as available on Iris.

Avoid UART input from floating RX pins on UARTB and UARTC (Colibri T30)
and UARTB, UARTC and UARTD (Apalis T30).
Note: Floating pins may cause spurious break conditions potentially
interrupting U-Boot's autoboot.
