Intel Braswell supports i2c block writes using SMBus controller.
This support is missing in actual smbus routines.
Add do_i2c_block_write() which is a based on do_smbus_block_write() but
also write first byte to SMBHSTDAT1.
The caller needs to configure the SMBus controller in i2c mode.
In i2c mode SMBus controller will send the next sequence:
SMBXINTADD, SMBHSTDAT1, SMBBLKDAT .. SMBBLKDAT
To ensure the the command is send over the bus the SMBHSTCMD register must
be written also

The SPI swseq controller can be locked in other parts of the code, for
instance when it's locked down in the finalize section. The driver
has to be made aware of that. The simpler solution is to not keep
track of the state and simply read out the lock bit on each SPI
transfer.
