In case CONFIG_SECURE_BOOT is enabled we need to limit the SPL size to
avoid a possible HAB failure event:

0x00 0x00 0x00 0x0f 0x00 0x90 0x70 0x00

STS = HAB_FAILURE (0x33)
RSN = HAB_INV_ADDRESS (0x22)
CTX = HAB_CTX_TARGET (0x33)
ENG = HAB_ENG_ANY (0x00)
As explained in Commit 23612534fe ("spl: imx6: Provide a SPL_SIZE_LIMIT
default") the i.MX6 SPL size limit is 68KB.
The ROM code is copying the image size defined in boot data to its
respective load address, in case we exceed the OCRAM free region a
HAB invalid address failure event is generated.
The maximum CSF size is defined in CONFIG_CSF_SIZE, reduce SPL size

The following options can be safely removed to save some precious
SPL space:
- CONFIG_SPL_FS_EXT4: u-boot-dtb.img is stored in raw sector via dd
command (at offset 69 kB)
- CONFIG_SPL_I2C_SUPPORT: I2C is not used during SPL
- CONFIG_SPL_OS_BOOT: no need to make Falcon mode supported
by default

Previously the SPL size on all iMX6 platforms was restricted to 68KB
because the OCRAM size on iMX6SL/DL parts is only 128KB. However, the
other iMX6 variants have 256KB of OCRAM. Add an option
CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
don't need to support the SL/DL variants. This allows for an SPL size of
196KB, which makes it much easier to use configurations such as SPL with
driver model and FDT control.
