conf: machine: am62*: extend picking common overlays by prefix

commit f5851386 ("conf: machine: am62*: Pick common overlays by prefix")
picks common HDMI and CSI overlays for am62 platform variants.

Adding capability to extend the same prefix for common overlays for applicable
am62 platforms in more generic way to include new mcan overlays added [1]

[1]: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/?&id=3b01c392627f

given the differences in SK-AM62-LP containing  B2B HDMI Samtec connector,
just added the kernel prefix to pick common mcan overlay.

for am62pxx: It has 4 MCANs vs all other am62xx devices have 3 MCANs,
hence keeping this prefix seperate for am62pxx to pick right overlay.
