[PATCH 0/2] usb: dwc3: Add cache type configuration support for freescale layerscape

[Frank Li]

There are several attempt to upstream this code in past year.

The first attempt:
https://lore.kernel.org/linux-usb/20191121095356.GB7503@b29397-desktop/

cache type is dwc core setting, not glue layer. So It'd better change in
dwc core instead of glue layer code.

The second attempt:
https://lore.kernel.org/linux-usb/20240123170206.3702413-1-Frank.Li@xxxxxxx/#t

DT team think there are not variable for property 'snps,dat-wr-reqinfo'.
And suggest use vendor compatible string.

This is third attempt:
Compared with first attempt:
- reduce compatible string to one 'fsl,ls-dwc3' because all setting are the
same.
- move update burst type code into dwc3_set_incr_burst_type(). and check
compatible string 'fsl,ls-dwc3'.
- Using bit field help macro.
