[PATCH 3/3] ARM: OMAP: I2C: fix compilation when !CONFIG_OF

[Paul Walmsley]

Commit 6145197be6cc0583fa1a2f4ec1079d366137061e ("i2c: OMAP: Add DT
support for i2c controller") breaks compilation when CONFIG_OF is not
defined:

  CC      drivers/i2c/busses/i2c-omap.o
drivers/i2c/busses/i2c-omap.c: In function 'omap_i2c_probe':
drivers/i2c/busses/i2c-omap.c:1021:26: error: 'omap_i2c_of_match' undeclared (first use in this function)
drivers/i2c/busses/i2c-omap.c:1021:26: note: each undeclared identifier is reported only once for each function it appears in

Fix this by avoiding of_*() functions when !CONFIG_OF.
