[PATCH v8 phy-next 04/31] usb: add missing headers transitively included by <linux/phy/phy.h>

The chipidea ci_hdrc_imx driver uses regulator consumer API like
regulator_enable() but does not include <linux/regulator/consumer.h>.

The core USB HCD driver calls invalidate_kernel_vmap_range() and
flush_kernel_vmap_range(), but does not include <linux/highmem.h>.

The DWC3 gadget driver calls:
- device_property_present()
- device_property_count_u8()
- device_property_read_u8_array()
but does not include <linux/property.h>

Similarly, dwc3-imx uses device_property_read_bool() without including
<linux/property.h>.

The dwc3-generic-plat driver uses of_device_get_match_data() but does
not include <linux/of.h>.

In all these cases, the necessary includes were still provided somehow,
directly or indirectly, through <linux/phy/phy.h>. I found the following
command to be quite helpful in figuring out the include chain:

$ make KCFLAGS="-H" drivers/usb/dwc3/dwc3-imx.o

Since <linux/phy/phy.h> wants to drop the unnecessary includes, fill in
the required headers to avoid any breakage.

v7->v8: none
v6->v7:
- add drivers/usb/dwc3/dwc3-imx.c to the list of patched files
- collect tag from Greg, keeping it despite the new addition because the
  change is minor and in the same spirit as the rest
(https://lore.kernel.org/linux-phy/2026033028-squint-yield-4c23@gregkh/)
v2->v6: none
v1->v2: collect tag
