fdt: Fix bug in size calculation in fdt_resize() with initrd use
Original bug description from Feng (fdt_resize() bug caused "WARNING:
could not set linux, initrd-start FDT_ERR_NOSPACE."):
What I got is an error: "WARNING: could not set linux,initrd-start
FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused
linux to miss init part.
After some digging, I found out the reason for this error, it is caused
by fdt_resize().
FDT blob got resized after filling in all board specific information of
PowerPC. (in boot_body_linux()). It reduced blob size with only extra
space for two fdt_reserve_entry, one for fdt itself, and one for initrd.
Then it's aligned to a 0x1000 page boundary. However, later in
fdt_initrd(), it could add two more properties, initrd-start AND
initrd-end, each one needs at least two fdt_reserve_entry sizes done by
_fdt_add_property() (name and value). Thus, the two fdt_reserve_entry
extra space is not sufficient.
So for some specific fdt size which is just under the page boundary
after resizing, this will cause an error of FDT_ERR_NOSPACE in
fdt_initrd() when setting those two properties, and failed to pass
initrd information to linux.
My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for
initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for
actual_totalsize, use 5*sizeof(struc fdt_reserve_entry).
Stefan: I got this same error on katmai, when trying to boot with
initrd (run flash_self). This patch fixes this issue.

fdt relocate: have more attention to use a bootmap or not

boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined
together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c).
On MicroBlaze platforms there is no need to use a bootmap to relocate
a fdt blob. So we need a more precise focus on the compilation and usage
of boot_relocate_fdt().
In general it is valid to exclude the function boot_relocate_fdt() if
the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined.

While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function. This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
