svn commit: r290410 - stable/10/sys/boot/amd64/efi

Log:
  MFC 287934:
  The EFI boot loader allocates a single chunk of contiguous memory to
  hold the kernel, modules, and any other loaded data.  This memory block
  is relocated to the kernel's expected location during the transfer of
  control from the loader to the kernel.
  
  The GENERIC kernel on amd64 has recently grown such that a kernel + zfs.ko
  no longer fits in the default staging size.  Bump the default size from
  32MB to 48MB to provide more breathing room.
