[PATCH] arm64: defconfig: increase SERIAL_8250_NR_UARTS

[Francesco Dolcini]

Increase CONFIG_SERIAL_8250_NR_UARTS from 4 to 8, the current legacy value
is not adequate for embedded systems that use SoCs where it's common to
have a large number of serial ports.

No need to change CONFIG_SERIAL_8250_RUNTIME_UARTS, see commit 9d86719f8769
("serial: 8250: Allow using ports higher than SERIAL_8250_RUNTIME_UARTS").

This enables using the UART connected Bluetooth device on Verdin AM62
board.
