[U-Boot] [PATCH] drivers: usb: gadget: ether: Fix compiler warning

[Lokesh Vutla]

Latest gcc 6.2 compiler is throwing the below warning for am335x_baltos_defconfig
drivers/usb/gadget/ether.c:501:17: warning: 'mdlm_detail_desc' defined but not used [-Wunused-const-variable=]
 static const u8 mdlm_detail_desc[] = {

Guard mdlm_detail_desc with CONFIG_USB_ETH_SUBSET to avoid the warning
