To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs to be given to resetb pin of ULPI chip. In ZYNQMP, this resetb pin is being driven by BOOT MODE PIN 1. The BOOT MODE PIN's are controlled by BOOT_PIN_CTRL register present in CRL_APB address region. Since CRL_APB can be resticted to secure access, this pin should be controlled by ATF.
This patch adds the support for the same.
