[PATCH] arm64: defconfig: Increase the maximum number of 8250/16550 serial ports

[Aswath Govindraju]

On some TI SoCs the number of UART instances used can be greater than 4.
For example in TI's J721S2 SoC, 11th instance of UART is used as console.
So, increase the maximum number of instances to 16.
