[PATCH v3 4/5] hw/loongarch: Set minimium memory size as 256M

[Bibo Mao]

The minimum memory size for LoongArch UEFI bios is 256M, also some
test cases such as migration and qos use 256M memory by default.

Here set minimum memory size for Loongarch VirtMachine with 256M rather
than 1G, so that test cases with 256M memory can pass to run.
