linux-yocto/4.1: fix musb compilation error
We had a partial musb change merged into the 4.1 tree, which resulted in:
| kernel-source/drivers/usb/musb/musb_dsps.c:
In function 'dsps_create_musb_pdev':
| kernel-source/drivers/usb/musb/musb_dsps.c:750:8:
error: 'struct musb_hdrc_config' has no member named 'maximum_speed'
| config->maximum_speed = usb_get_maximum_speed(&parent->dev);
| ^~
By backporting commit:
9b7537642cb6a [usb: musb: set the controller speed based on the config setting]
We get our missing structure field, and we can once again build musb.
