This converts the following to Kconfig:
   CONFIG_SYS_BOOTM_LEN

As part of this, rework error handling in boot/bootm.c so that we pass
the buffer size to handle_decomp_error as CONFIG_SYS_BOOTM_LEN will not
be available to host tools but we do know the size that we passed to
malloc().

The "autoload" environment variable is always checked with env_get_yesno
as it can be set to any form of no.  The default behavior of
env_get_yesno is to return -1 on variables that are not set, which acts
as true in general (we test for non-zero return).  To convert
CONFIG_SYS_AUTOLOAD to Kconfig, given that it was almost always used to
set autoload to no, first rename to CONFIG_SYS_DISABLE_AUTOLOAD for
consistency sake.  Then, make it so that if enabled we set autoload=0 in
the default environment.  Migrate all platforms which set
CONFIG_SYS_AUTOLOAD to non-true or that set autoload to false in their
default environment to using CONFIG_SYS_DISABLE_AUTOLOAD

With the exception of how PowerPC handles SPL and TPL (which has its own
issues), we cannot safely hide options under CONFIG_SPL_BUILD.  Largely
remove the places that have this test today.

As this is only useful when booting with ATAGs, which are now largely
disabled, remove this value for the remaining platforms.  We have a few
places in the code that had been testing for MACH_TYPE as a sort of
internal logic.  Update those to use different but still correct CONFIG
symbols.

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and
stemmy, disable ATAG support.  A large number of platforms had enabled
support but never supported a kernel so old as to require it.  Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years.  This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user.  When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts.  In other cases, these
functions were simply unused, so drop them.
