uboot-script-gen: Enable direct mapping of statically allocated memory
Direct mapping for dom0less VMs is disabled by default in XEN and can be
enabled through the 'direct-map' property.
Add a new config parameter DOMU_DIRECT_MAP to be able to enable or disable
direct mapping, i.e set to 1 for enabling and to 0 for disabling.
This parameter is optional. Direct mapping is enabled by default for all
dom0less VMs with static allocation.
The property 'direct-map' is a boolean property. Boolean properties are true
if present and false if missing.
Add a new data_type 'bool' in function dt_set() to setup a boolean property.
