cpm_uart/ subdirectory only has cpm_uart_core.c and cpm_uart.h now.
Move them up and remove cpm_uart/ directory while renaming
cpm_uart_core.c as cpm_uart.c

cpm_uart_map_pram() and cpm_uart_unmap_pram() are very
similar for CPM1 and CPM2.
On CPM1 cpm_uart_map_pram() uses of_iomap() while CPM2 uses
of_address_to_resource()/ioremap(). CPM2 version will also
work on CPM1.
On CPM2 cpm_uart_map_pram() and cpm_uart_unmap_pram() has a special
handling for SMC. Just gate it by an IS_ENABLED(CONFIG_CPM2).
So move the CPM2 version into cpm_uart_core.c which is the only
user of those two fonctions and refactor to also handle CPM1 as
mentionned above.
PROFF_SMC_SIZE is only defined for SMC2 and used only there. To make
it simple, just use the numerical value 64, this is the only place
it is used and anyway there's already the same numerical value for
the alignment.
Use cpm_muram_alloc() instead of cpm_dpalloc() macro.
Then cpm_uart_cpm1.c and cpm_uart_cpm2.c are now empty and go away.
Replace printk(KERN_WARN by pr_warn( to make checkpatch happier.

There were a few Kconfig and Makefiles under drivers/tty/ that were
missing a SPDX identifier. Fix that up so that automated tools can
properly classify all kernel source files.

Two config options exist to define powerpc MPC8xx:
* CONFIG_PPC_8xx
* CONFIG_8xx
In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as
communication co-processor
arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"
It looks like not many places still have that old CONFIG_8xx used,
so it is likely to be a good time to get rid of it completely ?

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
