mfd: kempld-core: Add support for additional devices 

This update includes DMI IDs for the following Kontron modules and
systems:
COMe-bDV7, COMe-cDV7, COMe-m4AL, COMe-mCT10, SMARC-sXAL, SMARC-sXA4,
Qseven-Q7AL, mITX-APL, pITX-APL and KBox A-203

Furthermore the ACPI HID KEM0000 is added, as it is also reserved for
kempld devices.

Instead of also adding the newly supported devices to the Kconfig
description this patch removes the lengthy list. With future usage of
the ACPI HIDs it will not be necessary to explicitly add support for
each individual device to the driver and therefore the list would
become incomplete anyway.

This is the core driver for the PLD (Programmable Logic Device) found
on some Kontron ETX and COMexpress (ETXexpress) modules. The PLD
device may provide functions like watchdog, GPIO, UART and I2C bus.
The following modules are supported:
* COMe-bBD#
* COMe-bBL6
* COMe-bHL6
* COMe-bSL6
* COMe-bIP#
* COMe-bKL6
* COMe-bPC2 (ETXexpress-PC)
* COMe-bSC# (ETXexpress-SC T#)
* COMe-cAL6
* COMe-cBL6
* COMe-cBT6
* COMe-cBW6
* COMe-cCT6
* COMe-cDC2 (microETXexpress-DC)
* COMe-cHL6
* COMe-cKL6
* COMe-cPC2 (microETXexpress-PC)
* COMe-cSL6
* COMe-mAL10
* COMe-mBT10
* COMe-mCT10
* COMe-mTT10 (nanoETXexpress-TT)
* ETX-OH
on some Kontron ETX and nearly all COMexpress (ETXexpress) modules as
well as on some other Kontron products. The PLD device may provide
functions like watchdog, GPIO, UART and I2C bus.
This driver can also be built as a module. If so, the module
will be called kempld-core.
