keystone: usb: add support of second usb host controller
Different TI Keystone2 SOCs support different number of
USB controllers. K2E supports 2 while K2H or K2L support
only one.
This patch adds simultaneous support of 2nd usb controller
in host mode on K2E. Number of usb controllers present is
defined by CONFIG_USB_MAX_CONTROLLER_COUNT found in respective
platform evm header file.
Since the usb connector on K2E EVM for the 2nd controller
is an USB3.0 micro AB connector, an adapter is needed in
order to use the 2nd controller in host mode.
