Commit 4d17aeb1

 ("OMAP: I2C: split
device registration and convert OMAP2+ to omap_device") broke I2C on
OMAP1.  The following messages appear at boot:

i2c_omap i2c_omap.1: failure requesting irq 0
i2c_omap: probe of i2c_omap.1 failed with error -22

Investigation revealed that a chunk of code is missing from the
original plat-omap/i2c.c file which configured the IRQ and base address
for the I2C block on OMAP1.  Upon adding this back, the OMAP1 I2C block
seems to initialize correctly.

Thanks to Cory Maccarrone <darkstar6262@gmail.com> for reporting the bug,
and apologies for the breakage.
