ipq40xx: fix I2C pin config on Aruba AP-303H

Turn on SoC pull-ups on I2C pins, since there are no discrete pull-up
resistors on the bus.

Increase clock to 400 kHz. Both chips on the bus support 400 kHz. I
tested the ISL28022 at 4,000 reads/sec and didn't see any garbled output
or bus hangs, even with SoC drive strength reduced to 2 for the test.
