Ben Lok ee6663563d stm32: spi: clear the spi sleep mask when AP in S3. ...

The SLEEP_MASK_SPI will not be cleared, if SPI received a bad data.
It is possible to block EC to enter deep sleep if AP send a bad
packet to EC before AP goto S3/S5. In order to ensure that deep
sleep can be enabled, clear SLEEP_MASK_SPI in chipset suspend hook
to avoid this situation.

BUG=chrome-os-partner:44170
BRANCH=None
TEST=manually
1. use AP console command to let AP enter S5:
   > shutdown -h now
2. check the sleepmask in EC console.
   > sleepmask
   sleep mask: 00000000
