part: efi: Add a Kconfig option for the number of partition entries
On some SoCs, the SPL needs to be located right in the middle of the GPT partition entries. One way to work around that is to create partition entries for a smaller number of partitions to accomodate with where the SPL will be. Create a Kconfig option to allow to do that.
