arc: make sure _start is in the beginning of .text section

This is important to have entry point in the beginning of .text section
because it allows simple loading and execution of U-Boot.

For example pre-bootloader loads U-Boot in memory starting from offset
0x81000000 and then just jumps to the same address.

Otherwise pre-bootloader would need to find-out where entry-point is. In
its turn if it deals with binary image of U-Boot there's no way for
pre-bootloader to get required value.

env_sf: Fix recovery default

The u-boot environment is redundantly stored in a NOR flash on our boards.
Redundant means that there are two places to store the environment. But only
one of the two is active. I discovered that on one board the u-boot (env_sf)
uses the environment from the second place and the Kernel (fw_printenv) uses
the environment from the first place.
To decide which is the active environment there is a byte inside the
environment. 1 means active and 0 means obsolete. But on that board both
environments had have a 1. This can happen if a power loss or reset occurs
during writing the environment. In this situation the u-boot (env_sf)
implementation uses the second environment as default. But the Kernel
(fw_printenv) implementation uses the first environment as default.

This commit corrects the default in the u-boot env_sf implementation when a
problem was detected. Now the recovery default is the same like in all other
environment implementations. E.g. fw_printenv and env_flash. This ensures that

Even though board_init_f_mem() has nothing to do with any particular
architecture it won't work (at least in current implementation) for X86.

This is because on X86 "gd" is an alias to function get_fs_gd_ptr(),
thus we cannot assign anything to it.

So this change separates selection of board_init_f_mem() from X86 while
