intel/fsp_baytrail: Use read32() and write32() in i2c.c

i2c.c uses "*(volatile unsigned int *)" constructs where it could use
read32() and write32().
Switch to using read32() and write32().

The remaining instances in wait_tx_fifo() and wait_rx_fifo() are fixed
in https://review.coreboot.org/#/c/14160/

I also fixed a few minor white space issues.
