Subject: [PATCH v1] EHCI: Fix endian access issue on EHCI intinalization

From: yinbo.zhu <yinbo.zhu at nxp.com>

This issue is exposed after commit 9000eddbase0d
("drivers/usb/ehci: Use platform-specific accessors"), the wrong endian way of EHCI controller programing will cause USB function down.

Configs Affected: P2041-40-R2.0, P3041-R2.0, P4080-40-R3.0, P5040-21-R2.1, T1024-R1.0, T1040-42-20-22-R1.1, T2080-R1.1, T4240-4160-R2.0
