From Micron, 512MB onwards, flash requires to poll flag status
instead of read status- hence added E_FSR flag on spectific
flash parts.

Few of the flashes(Atmel, Macronix and SST) require to
clear BP# bits in flash power ups.
So clear these BP# bits at probe time, so-that the flash
is ready for user operations.

Most of the SST flashes needs to write up using SST_WP, AAI
Word Program, so added a flag param on spi_flash_params table.
SST flashes, which supports SST_WP need to use a WP write
sst_write_wp instead of common flash write.

Divided the spi_flash framework into mutiple parts for
- spi_flash.c:
spi flash core file, interaction for spi/qspi driver to
spi_flash framework.
- spi_flash_ops.c
spi flash preffered operations, erase,write and read.
- spi_flash_probe.c
spi flash probing, easy to extend probing functionality.
This change will support to extend the functionality in a
proper manner.

This patch introduces SPL to enable a loader stub that being loaded by
the code from the internal on-chip ROM. It loads the final uboot image
into DDR, then jump to it to begin execution.
The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
ddr spd code can get the interleaving mode setting in env. It loads
final uboot image from offset 96KB.
* final uboot image, size is variable depends on the functions enabled.

Flag status register polling is required for micron 512Mb flash
devices onwards, for performing erase/program operations.
Like polling for WIP(Write-In-Progress) bit in read status register,
spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control)
bit in flag status register.
