[U-Boot] [PATCH 15/23] T4/USB: Add USB 2.0 UTMI dual phy support

[York Sun]

From: Roy Zang <tie-fei.zang at freescale.com>

T4240 internal UTMI phy is different comparing to previous UTMI PHY
in P3041.
This patch adds USB 2.0 UTMI Dual PHY new memory map and enable it for
T4240.
The phy timing is very sensitive and moving the phy enable code to
cpu_init.c will not work.
