aspeed: introduce a new UART0 device name
The Aspeed datasheet refers to the UART controllers
as UART1 - UART13 for the ast10x0, ast2600, ast2500
and ast2400 SoCs and the Aspeed ast2700 introduces an UART0
and the UART controllers as UART0 - UART12.
To keep the naming in the QEMU models
in sync with the datasheet, let's introduce a new UART0 device name
and do the required adjustements.

[ clg: - Kept original assert() in aspeed_soc_uart_set_chr()
- Fixed 'i' range in connect_serial_hds_to_uarts() loop ]
