Few changes to fix issues I've noticed while debugging omap5-uevm
wl18xx issues:
1. Move wlcore irq pin muxing under wlcore. This irq could be
different from gpio_wk14 on some board variants
2. Don't configure pull on wlcore irq pin. There is a 10k
pull up resistor R105 on the device to VDDS_1v8_MAIN
3. The padconf register for wlsdio_data1 is wrong, it's really
at 0x1a8 + 2 - 0x40 = 0x16a offset, not at 0x168 as that's
for wlsdio_data0
4. Mark the omap5-uevm wlan as compatible with ti,wl1837 as
that's what the TDK R078 part seems to be
Unfortunately all these changes still have no effect on getting
WLAN to work on omap5-uevm. I still keep getting constant errors
with wl12xx_queue_recovery_work.
