Underscores should not be used in node names (dtc with W=2 warns about
them), so replace them with hyphens.

Update its unit name to oscillator-26m and remove the unneeded unit
address to fix a unit_address_vs_reg warning.

Node names are supposed to match the class of the device. The
mmsys node is a syscon as it provides more then just a clock controller.
Update the name.

Add I2C support for Mediatek MT6797 SoC. There are a total of 8 I2C
controllers in this SoC (2 being shared) and they are same as the
controllers present in MT6577 SoC. Hence, the driver support is added with
DT fallback method.
As per the datasheet, there are controllers with _imm prefix like i2c2_imm
and i2c3_imm. These appears to be in different memory regions but sharing
the same pins with i2c2 and i2c3 respectively. Since there is no clear
evidence of what they really are, I've adapted the numbering/naming scheme
from the downstream code by Mediatek.

The nodes with name scpsys actually implement a power-controller.
Rename the nodes to match the bindings description.
