Jerzy Kasenberg d36bfddc30 DA146xx: Allow transmitting of packets larger then 64 bytes
FIFO is limited to 64 bytes yet MCU is capable of transmitting
larger packets provided that FIFO will be filled on the fly
and USB_USB_TXCx_REG_USB_LAST_Msk bit is set after FIFO is
filled with all the data that should be transmitted.

This change allows to use FIFO level warning interrupt to fill
FIFO. When DMA is available it will be used instead of interrupts.
Some function names were changed to better reflect what each function
does.
