Unlike i.MX53, i.MX51's USBOH3 register file does not implemenent
registers past offset 0x018, which includes
MX53_USB_CLKONOFF_CTRL_OFFSET and trying to access that register on
said platform results in external abort.

Fix it by enabling CLKONOFF accessing codepath only for i.MX53.

The internal 60Mhz clock for host2 and host3 are useless in ULPI
phy mode, so we disable it when configuring ULPI PHY node for
those host.

In order to use ULPI phy with usb host 2 and 3, we need to configure
controller register to enable ULPI features.

Each USB controller have different behaviour, so in order to avoid to have
several "swicth(data->index)" and lock/unlock, we prefer to get the index
switch and then test for features if they exist for this index.
This patch also remove useless test of reg and val. Those two values cannot
be NULL.

imx usb over current polarity is low active by default, with
over-current-active-high property added, user can config it to be high
active. Meanwhile keep this setting unchanged for existing platforms
so new platform must set the right value for active low by its usbmisc
init function if over current is enabled.

of_match_device could return NULL, and so cause a NULL pointer
dereference later. Renaming tmp_dev to of_id (like all others do) in the
process.

With this setting and AHBBRST at SBUSCFG as "Incremental burst of

transfer. It is benefit for non-burst size transfer.
