This patch set convert to use APIs leading with dev_ or ofnode_ which
supports live DT instead of fdt_ or fdtdec or devfdt_.
Two functions update there parameter from offset to ofnode:
- usb_get_maximum_speed()
- usb_get_dr_mode()

For V3 update:
Squesh patch 3rd~9th/9 into one patch because the ofnode_to_offset(node) is
not work with the livetree, so we have to convert the api to support
livetree and its related function at the same time.

For V2 update:
Drop below patch after include ofnode.h in otg.h:
[PATCH 09/10] usb: Use ofnode as usb_get_dr_mode() parameter


Changes in v3:
- Squesh the 3rd~9th into one patch.

The fdtdec.h is no use in this file, remove the include code.

Use dev_read_addr_ptr() instead of devfdt_get_addr() so that we can support
live DT.

* [PATCH v3 3/3] usb: Migrate to support live DT for some driver

Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

* [PATCH v3 3/3] usb: Migrate to support live DT for some driver
@ 2020-03-04  0:59   ` Kever Yang

Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

Changes in v3:
- Squesh the 3rd~9th into one patch.
