Fix the maximum brightness being much too low on the Yoga Tab 3 Pro.

The LP8557 backlight controller can either be configured to multiply its
PWM input and the I2C register set level (requiring both to be at 100%
for 100% output); or to only take the I2C register set level into account.

Multiplying the 2 levels is useful because this will turn off the backlight
when the panel goes off and turns off its PWM output.

But on the YT3-X90F the panel's PWM output defaults to a duty-cycle of much
less then 100%, severely limiting max brightness. In this case the LP8557
should be configured to only take the I2C register into account and
the i915 driver must turn off the backlight separately using a VBT MIPI
sequence to turn off the backlight.

The I2C-core already has filtering to skip i2c_client instantiation for
LNXVIDEO acpi_device-s with I2cSerialBus resources, since LNXVIDEO devices
are not i2c_client-s and are handled by the acpi_video driver.

This filtering was added to i2c-core-acpi.c in commit 3a4991a9

 ("i2c:
acpi: Do not create i2c-clients for LNXVIDEO ACPI devices").

Now a similar problem has shown up where the SPI-core is instantiating
an unwanted SPI-device for a SpiSerialBus resource under a LNXVIDEO
acpi_device. On a Lenovo Yoga Tab 3 YT3-X90F this unwanted SPI-device
instanstantiation causes the SPI-device instanstantiation for the WM5102
audio codec to fail with:

[   21.988441] pxa2xx-spi 8086228E:00: chipselect 0 already in use

Instead of duplicating the I2C-core filtering in the SPI-core code, push
the filtering of SerialBus resources under LNXVIDEO acpi_device-s up into
the ACPI-core by adding the LNXVIDEO HID to ignore_serial_bus_ids[].

Note the filtering in the I2C-core i2c_acpi_do_lookup() function is still
necessary because this not only impacts i2c_client instantiation but it
also makes the I2C-core ignore the I2cSerialBus resource when checking what
the maximum speed is the I2C bus supports, which is still necessary.
