[Qemu-devel] [PATCH v1] spapr.c: Update qemu's maxcpus for pseries machine.

[Seeteena Thoufeek <s1seetee@linux.vnet.ibm.com>]

Need to adjust the max cpus supported number from error message since
it was conflicting with KVM's.

Steps to Reproduce:
1.boot up with
"-smp 64,maxcpus=102464,cores=8,threads=1,sockets=8"

qemu-kvm: Number of SMP CPUs requested (102464) exceeds max CPUs
supported by machine 'pseries-rhel7.4.0alt' (1024)

2. On KVM machine it shows

boot up with
"-m 6G,maxmem=300G,slots=256 -smp 64,maxcpus=1024,cores=8,threads=1
,sockets=128"

Number of hotpluggable cpus requested (1024) exceeds the maximum cpus
 supported by KVM (240)

It seemed that 1024 was useless since KVM only support 240 so far.
Hence,we need to adjust it to an reasonable value 240.
