Add the version of the EC in the Tolino Shine 2 HD
to the supported versions. It seems not to have an RTC
and does not ack data written to it.
The vendor kernel happily ignores write errors, using
I2C via userspace i2c-set also shows the error.
So add a quirk to ignore that error.
PWM can be successfully configured despite of that error.

mfd: Add base driver for Netronix embedded controller2021-03-10T11:06:27ZJonathan Neuschäferj.neuschaefer@gmx.net2021-01-24T21:41:23Zurn:sha1:eceae583930666a69ab805eee8e81f9699bf6930
The Netronix embedded controller is a microcontroller found in some
e-book readers designed by the original design manufacturer Netronix,
Inc. It contains RTC, battery monitoring, system power management, and
PWM functionality.
This driver implements register access and version detection.
Third-party hardware documentation is available at:
https://github.com/neuschaefer/linux/wiki/Netronix-MSP430-embedded-controller
The EC supports interrupts, but the driver doesn't make use of them so
far.
