[PATCH] i2c: sirf: move driver init from module_init to subsys_initcall

[Barry Song]

From: Xiaomeng Hou <Xiaomeng.Hou at csr.com>

if we initilize i2c bus by module_init, there are some devices which want
initialization earlier than i2c and could not do that in time, so move i2c
driver initilization to subsys_initcall and make i2c ready before devices
init.
