apalis_t30: pinmux: enable internal pull-up on mxm3 pin 37
While MXM3 pin 37 aka WAKE1_MICO is pulled up with 4.7 K on the Apalis
Evaluation board and 100 K on the Ixora carrier board a custom carrier
board may leave it floating which may cause an unintended high interrupt
load on the default wake-up key with which may cause a lower CPU
performance.
