v7 cover SPL: Add support to boot a partition type

This adds support for the spl to seach for and boot from an arbitrary partition type rather then a specific partition number. When USE_PARTITION_TYPE is enabled, spl will search for the partition type but fallback to the specified partition number.

SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION is moved to a Kconfig and header and defconfigs for the affected boards are updated.

Changes in v7:
-> set part type to 0xa2 only if socfpga selected and merge previously split
patch
Changes in V6:
-> Fix unneeded backslash
-> Move SPL socfpga Kconfig default to selec tin arch/arm/Kconfig -> Split out defconfig changes for affected boards into a separate patch

PATCH v7 1/2 SPL: add support to boot from a partition type

the socfpga bootrom supports mmc booting from either a raw image starting at 0x0, or from a partition of type 0xa2. This patch adds support for locating the boot image in the first type 0xa2 partition found.

Assigned a partition number of -1 will cause a search for a partition of type CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_TYPE and use it to find the u-boot image

Changes in v7:
- set part type to 0xa2 only if socfpga selected
Changes in V6:
- Remove unneeded backslash
Changes in V5:
- fix styling in if (..) per Tom's request
Changes in V4:
- Try search for partition type and failover to the defined partition number
Changes in V3:
- Add depends on DOS_PARTITION
- Ensure that PARTTION_TYPE defaults to non-zero
- Add ifdef around sys_ind in disk_partition structure
Changes in V2:
- Merge partition search into single partition function

PATCH v7 2/2 SPL: Move SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION to Kconfig

In reply to Dalon Westergreen

Added SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION and
SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION to Kconfig.

Due to SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION being moved to Kconfig the board defconfigs for db-88f6820-gp_defconfig kc1_defconfig and sniper_defconfig need to be updated.

Changes in v4:
- merge defconfig changes into single patch
Changes in v3:
- Split off defconfig changes for db-88f6820-gp_defconfig kc1_defconfig and sniper_defconfig into a separate patch
Changes in v2:
- Remove SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION from socfpga_common.h
- wrong ifdef around mmc_load_image_raw_partition should be CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION
