clk: of: fix clk_of_table generation ...

We used to collect all sections beginning with __clk_of_table_ in a single
section in the linker using KEEP(*(.__clk_of_table_*)). That the sentinel
entry ended up as the last entry was pure luck, but not always the case.

Instead of putting all entries in different sections we now put all entries
in the same section. Only the sentinel entry gets its own section and is
collected by the linker separately.

remove unused nlink_t ...

The nlink_t type is unused in barebox, so drop it. This prevents
compile failures when architectures use the generic posix_types.h
which no longer has __kernel_nlink_t defined.

Instead of letting all architectures define their own dma_addr_t use

architectures can select to define the width of dma_addr_t. The same
is done in the Kernel.

Merge branch 'for-next/of-device-id'

Merge branch 'for-next/mvebu'

of: use 'const void *' for struct of_device_id.data ...

Since 2011 barebox' of_device_id struct uses unsigned long type for data field:

    struct of_device_id {
            char *compatible;
            unsigned long data;
    };

Almost always struct of_device_id.data field are used as pointer
and need 'unsigned long' casting.

E.g. see 'git grep -A 4 of_device_id drivers/' output:

    drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = {
    drivers/ata/sata-imx.c- {
    drivers/ata/sata-imx.c-         .compatible = "fsl,imx6q-ahci",
    drivers/ata/sata-imx.c-         .data = (unsigned long)&data_imx6,
    drivers/ata/sata-imx.c- }, {

Here is of_device_id struct in linux kernel v4.0:

    struct of_device_id {
            char name[32];
            char type[32];
            char compatible[128];
            const void *data;
    };

Changing of_device_id.data type to 'const void *data' will increase
barebox' linux kernel compatibility and decrease number of 'unsigned
long' casts.

Part of the patch was done using the 'coccinelle' tool with the
following semantic patch:

linux/amba/bus.h: drop unusable amba_{g,s}et_drvdata macros ...

amba_{g,s}et_drvdata macros from linux kernel use
dev_{g,s}et_drvdata functions.

But in linux dev_get_drvdata() takes only one argument
while in barebox dev_get_drvdata() takes two arguments.
There is no dev_set_drvdata() in barebox at all.

So amba_{g,s}et_drvdata macros from linux are
unusable for barebox.

Commit b8a1bb1dd215 (pci: defer device registration until after bridge setup)
changed the activation order of devices, so that bridges above the devices could
be configured properly before activating the devices below. This commit failed
to acknowledge that there may be devices located directly on the root bus without
any bridge in between and so those devices would never get enabled.
