usb: musb: Fix hub port setting for SPLIT transactions
The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:
8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.
Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.
The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.

Assume the U-Boot configuration is shared among some similar boards.
If they are similar enough, the difference only appears in device
trees. The build procedure would be like this:
- Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a
- Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b
- Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c
In this case, the U-Boot image contains nothing about the DTB file name
it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this
purpose because it is painful to change it from "make menuconfig" for
each board.)
This commit allows to lookup the DTB file name based on the compatible
string and set it to "fdt_file" environment. Then "tftpboot $fdt_file"
will download the file we want.
