Chengfeng Ye 3259e2d878 i2c: bcm-iproc: Fix bcm_iproc_i2c_isr deadlock issue 
commit 4caf4cb1eaed469742ef719f2cc024b1ec3fa9e6 upstream.

iproc_i2c_rd_reg() and iproc_i2c_wr_reg() are called from both
interrupt context (e.g. bcm_iproc_i2c_isr) and process context
(e.g. bcm_iproc_i2c_suspend). Therefore, interrupts should be
disabled to avoid potential deadlock. To prevent this scenario,
use spin_lock_irqsave().
