2018-10-02serial: 8250_uniphier: remove unused "fifo-size" propertyMasahiro Yamada1-4/+0
The FIFO size of the UART devices is 64 on almost all UniPhier SoCs with the exception Pro4TV SoC (MN2WS0235), which used 128 FIFO size. However, Pro4TV SoC was never upstreamed, and out of production. So, this property has never been used in a useful way. Let's remove old unused code.
