Fix typo of commit d4e53f063dd25e071444b87303573e7440deeb89.
i2c2 pullup resisters are controlled by bit 0 of CONTROL_PROG_IO1.
It's value after reset is 0x00100001.
In order to clear bit 0, original code write 0xfffffffe to
CONTROL_PROG_IO1 and toggle almost all default values.
Original code affect following:
* disable i2c1 pullup resisters
* increase far end load setting for many modules
* setup invalid SC/LB combination
