usb: host: ehci-st: Remove set but not used variable 'ehci'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/host/ehci-st.c: In function st_ehci_platform_probe:
drivers/usb/host/ehci-st.c:155:19: warning: variable ehci set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
