Since this change we don't need to have custom solutions in 8250_aspeed_vuart and 8250_of drivers, thus, drop them.

For 4.14, I've worked around these missing commits:
5909c0bf9c7a ("serial/aspeed-vuart: Implement quick throttle mechanism") 989983ea849d ("serial/aspeed-vuart: Implement rx throttling") 54e53b2e8081 ("tty: serial: 8250: pass IRQ shared flag to UART ports")
Thanks!
And queued up a backport. Older kernels are a bit trickier than that.
Since it's quite old bug and not many reports so far I guess we are not in hurry to fix that old kernels.
