[NOTE: I'm reviving a bunch of patches that was in the process of
upstreaming a while ago but paused.]

This patch set contains a few bug fixes and I2C devices for some
NPCM7XX boards.

Patch 1~2 fix a problem that causes the SMBus module to behave
incorrectly when it's in FIFO mode and trying to receive more than
16 bytes at a time.

Patch 3 fixes a error in a register for ADC module.

Patch 4 makes the ADC input to be R/W instead of write only. It allows
a test system to read these via QMP and has no negative effect.

Patch 5 adds a new blockdev IF type IF_OTHER.

Patch 6 allows at24c_eeprom_init to take a bus as parameter so it can
be used by more use cases (e.g. behind an I2C mux.)

Patch 7 allows at24c_eeprom_init to take a drive as property, similar
to sdhci_attach_device().

Patch 8 uses the function defined in patch 5 to add the EEPROM and other
I2C devices for Quanta GBS board.

-- Changes since v4:
1. Add comments to patch 5.
2. Split patch 6 into 2 patches according to the feedback.  Each patch does it own task.

-- Changes since v3:
1. Add a new blockdev IF type IF_OTHER.
2. Use IF_OTHER instead of IF_NONE.

-- Changes since v2:
1. Dropped patch 7.
2. Drop an extra variable in patch 5.

-- Changes since v1:
1. Rewrote patch 5 to implement the function in NPCM7xx board file instead
   of the EEPROM device file.
2. Slightly modify patch 6 to adapt to the changes and QEMU comment style.
3. Squash patch 7 into patch 5 to make it compile.
4. Add a new patch 7.

I've taken patches 3 and 4 into target-arm.next as they're
already reviewed and standalone bugfixes. I had a comment on
patch 2. I'll leave the IF_OTHER patch (and the patches that
make use of it) to the blockdev folks to review.
