net: stmmac: dwmac4: Also use TBU interrupt to clean TX path
TBU interrupt is a normal interrupt and can be used to trigger the
cleaning of TX path. Lets check if it's active in DMA interrupt handler.
While at it, refactor a little bit the function:
- Don't check if RI is enabled because at function exit we will
only clear the interrupts that are enabled so, no event will be
missed.
In my tests with GMAC5 this increased performance.
