i2c: sh_mobile: Mark adapter suspended during suspend
When a driver tries to send an I2C message while the adapter is
suspended, this typically fails with:
i2c-sh_mobile e60b0000.i2c: Transfer request timed out
Avoid accessing the adapter while it is suspended by marking it
suspended during suspend. This allows the I2C core to catch this, and
print a warning:
WARNING: CPU: 1 PID: 13 at drivers/i2c/i2c-core.h:54
__i2c_transfer+0x4a4/0x4e4
i2c i2c-6: Transfer while suspended
