Also change some of the types to match the register widths
of the controller. It is expected that these prototypes
will be used with SMBus host controllers inside AMD chipsets
as well, thus the change of location.

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

Datasheets describe the used command as 'I2C Read' but adding the
word 'eeprom' in between should avoid further confusion with other
block commands.
Followups will add a symmetrical pair of commands i2c_block_read()
and i2c_block_write() that operate via I2C_EN bit and have a 32
byte size restriction on block transfers. For some hardware revision
these block commands are available, while 'I2C Read' was not.

All Intel southbridges implement the same SMBus functions.
This patch replaces all these similar and mostly identical
implementations with a common file.
This also makes i2c block read available to all those southbridges.
If the northbridge has to read a lot of SPD bytes sequentially, using
this function can reduce the time being spent to read SPD five-fold.
