elf64 entry is defined as a u64. Since boot_addr is used to store the
elf entry point, change boot_addr type to u64 to support both elf32
and elf64. In the same time, fix users that were using this variable.

The return type of function rproc_get_boot_addr() should also be changed from
u32 to u64.  Or perhaps this is intentional to make sure rproc->bootaddr never
occupies more than 32bit?

No, this is a mistake clearly. I haven't been able to test with a 64 bit
boot address since our remote processors always boot in the 32 bits
space. But since the elf64 boot address is on 64 bitsn this was a logical
modification. I will fix that.

Sorry, I forgot to reply to this one. I fixed it up while applying the
patch.
