Maxim MAX77802 is a power management chip that contains 10 high
efficiency Buck regulators, 32 Low-dropout (LDO) regulators used
to power up application processors and peripherals, a 2-channel
32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface
to program the individual regulators, clocks outputs and the RTC.

This patch adds support for MAX77802 to the MAX77686 driver and is
based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

We know how many bytes the EC should be sending us (which is also the
number of bytes transferred) and also how many bytes the EC actually
wanted to send to us.  When computing the checksum and copying back
data let's make sure we take the lesser of the two of those.  We'll
also complain if the EC tried to send us too many bytes.  The EC
sending us too few bytes is legit for when we send the EC an invalid
command.

This is based on similar code in cros_ec_spi.
