Vadim Bendebury 569b5e8f0f g: sps: add flow control signaling ...

The TPM SPI protocol adds flow control capability, but it is
impossible to enforce it by software, software implementations need
additional means of informing the master about the slave status.

Let's follow the i2c slave driver example and use the interrupt line
from the H1 to the SOC to generate a low level pulse every time
receive data processing is completed.

BRANCH=none
BUG=none
TEST=to benefit from this patch some changes on the SOC side will be
     required.
