Both Bay and Cherry Trail devices may be used together with a Crystal Cove
PMIC. Each platform has its own variant of the PMIC, which both use the
same ACPI HID, but they are not 100% compatible.
This commits makes the intel_soc_pmic_core code check the _HRV of the
ACPI-firmware-node and selects intel_soc_pmic_config_byt_crc resp.
intel_soc_pmic_config_cht_crc based on this.
This fixes the Bay Trail specific ACPI OpRegion code causing problems
on Cherry Trail devices. Specifically this was causing the external
microsd slot on a Dell Venue 8 5855 (Cherry Trail version) to not work
and the eMMC to become unreliable and throw lots of errors.

Both Bay and Cherry Trail devices may be used together with a Crystal Cove
PMIC. Each platform has its own variant of the PMIC, which both use the
same ACPI HID, but they are not 100% compatible.
Looking at the android x86 kernel sources where most of the Crystal Cove
code comes from, it talks about "Valley View", "Bay Trail" and / or BYT
without ever mentioning Cherry Trail, with the exception of the regulator
driver. The Asus Zenfone-2 kernel code has 2 regulator drivers, one
for Crystal Cove and one for what it calls Crystal Cove Plus. The
Crystal Cove Plus regulator driver is the only one to mention Cherry
Trail and that driver uses different register addresses then the
normal (Bay Trail) Crystal Cove regulator driver, showing that at
least the regulator register addresses are different.
The GPIO code should work on both, and the PWM code is known to work on
both and is necessary for backlight control on some Cherry Trail devices.
Testing has shown that the ACPI OpRegion code otoh is causing problems
on Cherry Trail devices, which is not surprising as it deals with the
regulators and those have different register addresses on CHT.
Specifically the ACPI OpRegion code causes the external microsd slot on
a Dell Venue 8 5855 (Cherry Trail version) to not work and the eMMC to
become unreliable and throw lots of errors.
This commit replaces the single mfd_cell array currently used for Crystal
Cove with 2 separate arrays, one for the Bay Trail variant and one for
the Cherry Trail variant, note that the Cherry Trail version of the array
only contains gpio and pwm cells. The PMIC OpRegion cell is deliberately
not included and drivers for the other cells in the Bay Trail cell array
were never upstreamed.

unction devm_regmap_init_i2c() returns an ERR_PTR on errors, and its
return value should be checked before it is dereferenced. However, in
function intel_soc_pmic_i2c_probe(), the return value of function
devm_regmap_init_i2c() is used without validation. This patch fixes it.

Since commit 845c877009cf ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") I2C core assigns interrupt line to I2C slave
devices with regarding to GpioInt() resources.
There is no need to repeat this in the driver.

GPIO lookup tables are supposed to be zero terminated. Let's do that

Pull drm updates from Dave Airlie:
"This is the main pull request for the drm for 4.3. Nouveau is
probably the biggest amount of changes in here, since it missed 4.2.

- new drivers:
freescale dcu kms driver
- core:
more atomic fixes
disable some dri1 interfaces on kms drivers

intel_soc_pmic_find_gpio_irq() tries to find a GPIO interrupt but doesn't
select between it or I2C interrupt so it makes more sense to move this
comment to intel_soc_pmic_i2c_probe() with minor edits.
