usb: renesas_usbhs: Remove renesas_usbhs_get_info() wrapper

The renesas_usbhs_get_info() wrapper was useful for legacy board code.
Since commit 1fa59bda21c7fa36 ("ARM: shmobile: Remove legacy board code
for Armadillo-800 EVA") in v4.3, it is no longer used outside the USBHS
driver, and provides no added value over dev_get_platdata(), while
obfuscating the real operation.

Drop it, and replace it by dev_get_platdata() in its sole user.
