[PATCH V1] mfd: rc5t583: Build only if I2C config is selected to y.

[Laxman Dewangan]

The rc5t583 driver requires the I2C and regmap apis to
link. But linking fails if I2C is selected as loadable
module, not the module link with binary.
Fixing this error as rc5t583 driver should be built only
if CONFIG_I2C=y.

Fixing build error reported by Stephen Rothwell:
After merging the mfd tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/built-in.o: In function `rc5t583_i2c_init':
rc5t583.c:(.init.text+0xb3db): undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `rc5t583_i2c_probe':
rc5t583.c:(.devinit.text+0x8fa0): undefined reference to `regmap_init_i2c'
drivers/built-in.o: In function `rc5t583_i2c_exit':
rc5t583.c:(.exit.text+0x708): undefined reference to `i2c_del_driver'

Caused by commit 1b1247dd75aa ("mfd: Add support for RICOH PMIC
RC5T583"). Presumably some missing Kconfig dependency.
