Exposing set/way cache maintenance to a virtual machine is unsafe, not
least because the instructions are not permission-checked but also
because they are not broadcast between CPUs. Consequently, KVM traps and
emulates such maintenance in the host kernel using by-VA operations and
looping over the stage-2 page-tables. However, when running under
protected KVM, these instructions are not able to be emulated and will
instead result in an exception being delivered to the guest.
Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select
this option and perform by-VA cache maintenance instead of using the
set/way instructions.

Marvell BootROM loads MMC image from sector 0 (HW boot or data partition)
and SD image from sector 1.
So for SD card booting it is needed to not use constant CONFIG MMC options
and instead of them it is needed to define functions spl_mmc_boot_mode()
spl_mmc_get_uboot_raw_sector() which determinate offsets at SPL runtime
based on MMC or SD card.
Calculation of SD card sector expects following values:
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET=0
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0
