The current compatible strings for SSD130x I2C controllers contain both an
"fb" and "-i2c" suffixes. It seems to indicate that are for a fbdev driver
and also that are for devices that can be accessed over an I2C bus.
But a DT is supposed to describe the hardware and not Linux implementation
details. So let's deprecate those compatible strings and add new ones that
only contain the vendor and device name, without any of these suffixes.
These will just describe the device and can be matched by both I2C and SPI
DRM drivers. The required properties should still be enforced for old ones.
While being there, just drop the "sinowealth,sh1106-i2c" compatible string
since that was never present in a released Linux version.

The SINO WEALTH SH1106 is an OLED display driver that is somewhat
compatible with the SSD1306. It supports a slightly wider display,
at 132 instead of 128 pixels. The basic commands are the same, but
the SH1106 doesn't support the horizontal or vertical address modes.
Add a compatible string for it.
