FIT image supports more than 32 bits in addresses by using #address-cell field. However the address length is not handled when parsing FIT images. Beside, the variable used to host address has "ulong" type. It is OK for the target, but not always enough for host tools such as mkimage. This patch replaces "ulong" with "phys_addr_t" to make sure the address is correct for both the target and the host.

Changes in v3: Define PRIpa for host and target in common/image-fit.c so printf works properly for 32-, 64-bit targets and host tools.
Changes in v2: Make a common function for both load and entry addresses. Simplify calculation of addresses in a similar way as fdtdec_get_number() fdtdec_get_number() is not used, or too many files need to be included and/or twisted for host tool Continue to use %08llx for print format for load and entry addresses because %pa does not always work for host tool (mkimage)
