Setting the memory size of dom0 on a server for the non autoballooning case requires always specification of a boot parameter today. The value to set will depend mostly on the host memory size.
In order to support that scenario add the possibility to set dom0_mem depending on the amount of physical memory by allowing to specify a percentage of host memory (e.g. 10%) with an offset (like 1G+10%). To make it easy for a distributor to use such a setting as the default make the standard setting for dom0_mem configurable via Kconfig.
