We like to put the SPL first so it is clear that it relates to SPL. Rename
various malloc-related options which have crept in, to stick to this
convention.

In order to enable HAB, FSL_CAAM, ARCH_MISC_INIT and
SPL_CRYPTO should be enabled in Kconfig like other i.MX8M
boards.
This also needs to occur in the SPL so enable CONFIG_SPL_BOARD_INIT and
add a void spl_board_init function which calls arch_misc_init to probe
the CAAM driver.

To allow U-Boot to fit within emmc boot partitions move the env from
just under 16MiB to just under 4MiB as some emmc devices used on venice
boards have 4MiB boot partitions. This still leaves plenty of room for
U-Boot.

Add GPIO name lookup so that you can act on GPIO's by name vs controller
id:
Before:
u-boot=> gpio input pci_wdis#
GPIO: 'pci_wdis#' not found
Command 'gpio' failed: Error -22
After:
u-boot=> gpio input pci_wdis#
gpio: pin pci_wdis# (gpio 103) value is 1

This converts the following to Kconfig:
CONFIG_SYS_MONITOR_LEN
To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this
value. Update the SPL code to use 200 KB as the default raw U-Boot size
directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().
Rename it to resolve this problem.

When booting from USB/SDP mmc_get_env_dev() returns
CONFIG_SYS_MMC_ENV_DEV as the MMC env device (while booting from MMC
will call board_mmc_get_env_dev() to get this). Configure
CONFIG_SYS_MMC_ENV_DEV for SDHC3 (devno=2) as all Gateworks Venice
boards use SDHC3 as eMMC so that persistent env works when booting from
USB/SDP.

commit 970bf8603b ("Convert CONFIG_USE_BOOTCOMMAND et al to Kconfig")
had an unintended side effect of resulting in a bootcmd env var change
for boards like venice that did not have CONFIG_USE_BOOTCOMMAND defined
and relied on it being defaulted in include/config_distro_bootcmd.h.
Following that patch it instead got defaulted in tools/env/fw_env_private.h
Fix this by enabling CONFIG_USE_BOOTCOMMAND for venice.

The CONFIG_SPL_MAX_SIZE could be 0x27000 for i.MX8MM when SPL_TEXT_BASE
set to 0x7E1000.
The DDR firmware max uses 96KB, there is a 4KB padding header before
SPL_TEXT_BASE, so the SPL MAX SIZE is `256KB - 96KB - 4KB`.

This converts the following to Kconfig:

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 uart2 and its pinmux are already marked with u-boot,dm-spl but we
need to move the call to preloader_console_init() after spl_early_init()
to avoid a board hang as dm can't be used until after spl_early_init()
due to the uart driver not enabling the uart clock.
Remove the manual config of the UART pinmux now that it is no longer
needed.

Add gpio hog support for board-specific gpio lines:
- put hogs in u-boot.dtsi so as to keep the regular dts files
in sync with the kernel. The hogs will not be put in the kernel
as that makes them un-usable by userspace as well as
re-initializes them to dt defaults overriding changes which may
have been done by bootloader commands.
- specify gpio names and initial config
- enable GPIO_HOG
