[PATCH v2 1/2] usb: ohci: s3c2410: Drop support for S3C2410 systems

[Krzysztof Kozlowski]

Samsung S3C24xx family of SoCs was removed the Linux kernel in the
commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support"), in January
2023.  There are no in-kernel users of remaining S3C24xx compatibles.

The driver (named s3c2410) is still being used via platform code for
S3C64xx platforms.

-Samsung S3C2410 and compatible SoC USB controller

-OHCI
-
-Required properties:
- - compatible: should be "samsung,s3c2410-ohci" for USB host controller
- - reg: address and length of the controller memory mapped region
- - interrupts: interrupt number for the USB OHCI controller
- - clocks: Should reference the bus and host clocks
- - clock-names: Should contain two strings
-		"usb-bus-host" for the USB bus clock
-		"usb-host" for the USB host clock

-
-usb0: ohci@49000000 {
