Current flash wait_ready logic is not modular to add new
register status check, hence updated the status check for
adding few more register checks in future.

Define CONFIG_SYS_SPI_ARGS_OFFS, CONFIG_SYS_SPI_ARGS_SIZE
and CONFIG_SYS_SPI_KERNEL_OFFS which will be used in SPL
spi mode. These macros defines the device tree offset, size
and the kernel image offset in flash respectively.

priv->mode is initialized when .set_speed triggers
with mode value, so checking mode for configuring
CPOL, CPHA using priv->mode is invalid hence use
mode from .set_speed argument, and at the end
priv->mode will initialized with mode.
This patch also replaces formatting string to use
speed instead of mode in .set_speed ops.

We have finished Generic Board conversion for ARM and PowerPC, i.e.
all the boards have been converted except OpenRISC, SuperH, SPARC,
which have not supported Generic Board framework yet.
Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro
defines in include/configs/*.h.

We should not init the console this early since it precludes using driver
model for the UART, since it is not set up at the start of board_init_f().
See the README for more information. The debug UART does not have this
restriction. If we want to do early init with the console on it can be done
in spl_board_init().
Move the preloader_console_init() call from board_init_f() to board_init_r().

There is quite a bit of assembler code that can be removed if we use the
generic global_data setup. Less arch-specific code makes it easier to add
new features and maintain the start-up code.
Drop the unneeded code and adjust the hooks in board_f.c to cope.

This function will be used by both SPL and U-Boot proper. So move it into
a common place. Also change the #ifdef so that the early malloc() area is
not set up in SPL if CONFIG_SYS_SPL_MALLOC_START is defined. In that case
it would never actually be used, and just chews up stack space.

In the following snippet:
if [ ! -x `which $prereq` ]; then
When $prereq does not exist, `which $prereq` evaluates to the empty string,
which results in *no* argument being passed to the -x operator, which then
evaluates to true, which is the equivalent of the prereq having been found. In
order for this to fail as expected, we must pass an empty argument, which then
causes -x to fail. Do this by wrapping the `` in quotes so there's always an
argument to -x, even if the value of the argument is zero-length.
