usb: ehci-omap: drop unused ehci_read() function

After moving the omap1 platform into generalized multiplatform
support on ARM, the kernel test robot points out a W=1 warning that
now shows up in more configurations:

drivers/usb/host/ehci-omap.c:64:19: warning: unused function 'ehci_read'

The function was last used 9 years ago and can just be removed.
