ARM: dts: blanche: Configure pull-up for SOFT_SW and SW25 GPIO keys

Browse source

The GPIO pins connected to the 4 Software Switches (SW2) and the second
Tact Switch (SW25) do not have external pull-up resistors, but rely on
internal pull-ups being enabled.  Fortunately this is satisfied by the
initial state of these pins.

Make this explicit by enabling bias-pull-up, to remove the dependency on
initial state and/or boot loader configuration.

Note that the GPIO pin connected to the first Tact Switch (SW24) does
have an external pull-up resistor.
