[PATCH 1/2] i3c: master: svc: fix compatibility string mismatch with binding doc

[PATCH 1/2] i3c: master: svc: fix compatibility string mismatch with binding doc

[Frank Li]

In the binding documentation, the compatible string is specified as
'silvaco,i3c-master-v1', but in the driver, it is defined as
'silvaco,i3c-master'.

Add 'silvaco,i3c-master-v1' to the driver and deprecates
'silvaco,i3c-master' to ensure compatibility with the documentation.

Notes:
    Change from v1 to v2
    - update driver by using compatible string silvaco,i3c-master-v1

The real problem here is not whether we have "v1" or not, but you need 
an SoC specific compatible. Unless there's a public spec where we can 
know exactly how many resets, clocks, interrupts, etc.
