tty: serial: sh-sci: Add default for number of ports for compile-testing
When compile-testing an allmodconfig kernel for a platform without
sh-sci serial ports, the SERIAL_SH_SCI_NR_UARTS symbol of type "int"
doesn't get assigned a numerical default value, but an empty string,
leading to a build failure:
.config:3814:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS
...
make[3]: *** [silentoldconfig] Error 1
Fix this by explicitly providing a default value of 2, like before.

Fixes: f6731485a51978ca ("tty: serial: sh-sci: Hide number of ports config question")
