Add support for Xen boot-time cpupools

Introduce support for creating boot-time cpupools in the device tree and
assigning them to dom0less domUs. Add the following options:
 - CPUPOOL[number]="cpu@1,...,cpu@N scheduler" to specify the
   list of cpus' node names and the scheduler to be used to create cpupool
 - NUM_CPUPOOLS to specify the number of cpupools to create
 - DOMU_CPUPOOL[number]="<id>" to specify the id of the cpupool to
   assign to domU

Example usage:
CPUPOOL[0]="cpu@1,cpu@2 null"
DOMU_CPUPOOL[0]=0
NUM_CPUPOOLS=1

The above example will create a boot-time cpupool (id=0) with 2 cpus:
cpu@1, cpu@2 and the null scheduler. It will assign the cpupool with
id=0 to domU0.
