ppc4xx: Fix GPIO handling in lwmon5 and lcd4_lwmon5 BSP
LCD4 needs a slightly different GPIO configuration than the original LWMON5 variant. GPIO49 needs to be configured to a default output value of 0 (permanent voltage supply). Additionally lcd4 also needs to enable the LSB transmitter. Signed-off-by: Stefan Roese <sr@denx.de>
