i3c: ast2600: Add AST2600 platform-specific driver

Now that we have platform-specific infrastructure for the dw i3c driver,
add platform support for the ASPEED AST2600 SoC.

The AST2600 has a small set of "i3c global" registers, providing
platform-level i3c configuration outside of the i3c core.

For the ast2600, we need a couple of extra setup operations:

 - on probe: find the i3c global register set and parse the SDA pullup
   resistor values

 - on init: set the pullups accordingly, and set the i3c instance IDs
