This patch adds SiFive SPI driver. The driver is 100% DM driver
and it determines input clock using clk framework.

The SiFive SPI block is found on SiFive FU540 SOC and is used to
access flash and MMC devices on SiFive Unleashed board.

This driver implementation is inspired from the Linux SiFive SPI
driver available in Linux-5.2 or higher and SiFive FSBL sources.

This patch extends MMC SPI driver to pass SPI_XFER_BEGIN flag when

The code block reading the DT property for the clock output control was
before the phy's DT node pointer was set, so it could never work.  Move
it after the node pointer is set.

Also store the unsigned 32-bit property into an unsigned value, not a
signed value, as the former will cause a problem if value overflows.
For instance, if one were to add 0xffffffff as a code to mean the clock
output should be turned off.

When not using DM_ETH, these PHY settings are programmed with default
values hardcoded into the driver.  When using DM_ETH, they should come
from the device tree.  However, if the device tree does not have the
properties, the driver will silent use -1.  Which is entirely out of
range, programs nonsense into the PHY's registers, and does not work.

Change this to use the same defaults as non-DM_ETH if the device tree is
lacking the properties.

As an alternative, the kernel driver for the phy will display an error
message and fail if the device tree is lacking.

Share the code that prints out a register field with the function that
prints out the "special" fields.

There were two arrays the register dump list, one with reg number and
name, another with a pointer to the field table and the table size.
These two arrays had have each entry match what register is referred to.
Combine them into just one table.  Now they can't not match and there is
just one table.

Add some missing consts to pointers to string literals.

The dump code was ignoring the regno field in the description table and
assuming register 0 was at index 0, etc.  Have it use the field.

Change reg > max+1 into reg >= max, which doesn't fail if max+1 could
overflow, besides just making more sense.

The choice of the SPL_TEXT_BASE is not really a decision that should be
specified by each board's defconfig, as this setting is actually
dictated by the SoC's memory map and the BootROM behaviour.

To make this obvious and reduce the clutter in the defconfig files,
let's specify the SoC constraints in the Kconfig stanza.
This allows us to remove these lines from the defconfig files again.
