dwc2: g_serial doesn't enumerate when builtin

Hi, this seems like a newbie question, but shouldn't g_serial also work in case it's builtin? I tested g_serial with a Raspberry Pi Zero (OTG mode, Linux 4.11-rc1) as gadget and a Linux Laptop as host (Linux 4.10.9). In case g_serial is build as a kernel module the RPi gets enumerated on the

[PATCH RFT] usb: dwc2: gadget: Fix fifo size configuration

Currently the upper limit for the endpoint index during fifo size config was always 16 instead of the available endpoints. So fix this by using the determined amount of endpoints and avoid a warning about "insufficient fifo memory" on bcm2835 which has only 8 endpoints. Signed-off-
