[PULL 01/37] hw/display/sm501: Always map the UART0

[Marc-André Lureau]

From: Philippe Mathieu-Daudé <address@hidden>

The SM501 is a Mobile Multimedia Companion Chip with 2 UARTs.
This model only implements the first UART. Being part of the
chipset, the UART block is always mapped in memory, regardless
of whether we provide a chardev backend.

Since commit 12051d82f, qemu_chr_fe_init() accepts a NULL chardev.
Let's remove the chardev check and always map the UART in the
chipset memory.
