[U-Boot] [PATCH] drivers: usb: dwc3: remove devm_zalloc from linux_compact

[Michal Simek]

From: Mugunthan V N <mugunthanvnm at ti.com>

devm_zalloc() is already defined in dm/device.h header, so
devm_zalloc can be removed from linux_compact.h beader file.

"linux-compat.h is local to dwc3 folder where as dm/device.h is available
globally. My understanding is linux-compat.h is to define
functions/wrappers needed by dwc3 part picked from linux that are not
yet directly available in U-Boot. But, given that devm_kzalloc() is
provided in U-Boot, I thought it would be better to get rid of
definition in linux-compat.h in order to avoid conflicting definition
error."
