target/riscv/cpu.c: fix machine IDs getters
mvendorid is an uint32 property, mimpid/marchid are uint64 properties.
But their getters are returning bools. The reason this went under the
radar for this long is because we have no code using the getters.
The problem can be seem via the 'qom-get' API though. Launching QEMU
with the 'veyron-v1' CPU, a model with:
VEYRON_V1_MVENDORID: 0x61f (1567)
VEYRON_V1_MIMPID: 0x111 (273)
VEYRON_V1_MARCHID: 0x8000000000010000 (9223372036854841344)
This is what the API returns when retrieving these properties:
(qemu) qom-get /machine/soc0/harts[0] mvendorid
true
(qemu) qom-get /machine/soc0/harts[0] mimpid
true
(qemu) qom-get /machine/soc0/harts[0] marchid
true
After this patch:
(qemu) qom-get /machine/soc0/harts[0] mvendorid
1567
(qemu) qom-get /machine/soc0/harts[0] mimpid
273
(qemu) qom-get /machine/soc0/harts[0] marchid
9223372036854841344
Fixes: 1e34150045 ("target/riscv/cpu.c: restrict 'mvendorid' value")
Fixes: a1863ad368 ("target/riscv/cpu.c: restrict 'mimpid' value")
Fixes: d6a427e2c0 ("target/riscv/cpu.c: restrict 'marchid' value")
