commit ca21f851cc9643af049226d57fabc3c883ea648e upstream.
The Acorn i2c driver (for RiscPC) triggers the "i2c adapter has no name"
warning in the I2C core driver, resulting in the RTC being inaccessible.
Fix this.

That path has gone away for a long time. Move the HW name upwards for a
proper header.

As of v4.15, Kbuild warns about missing MODULE_LICENSE tags:
WARNING: modpost: missing MODULE_LICENSE() in drivers/i2c/busses/i2c-acorn.o
This adds a license, author and description tag, matching the
comment at the start of the acorn i2c driver.

This file is controlled by a tristate Kconfig option, and hence
needs to include module.h so that it can get module_init() once
we relocate it from init.h into module.h in the future.
Note that module_exit() appears to be missing from the driver, so
it is questionable whether it would actually work for a removal
and reload cycle if it was configured for a modular build.

Remove all #inclusions of asm/system.h preparatory to splitting and killing
it. Performed with the following command:
perl -p -i -e 's!^#\s*include\s*<asm/system[.]h>.*\n!!' `grep -Irl '^#\s*include\s*<asm/system[.]h>' *`

i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers
should use set this value in terms of HZ.
Ultimately I think this field should be discarded in favor of
i2c_adapter.timeout, but that's left for a future patch.

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

It depends on tristate I2C and it's trivial to make modular. The
current Kconfig allows I2C=m, I2C_ACORN=y, which doesn't work at
all; alternatives are dependency on I2C=y and making I2C_ACORN
itself a tristate. The latter is the right thing to do...

Move the Acorn IOC/IOMD I2C bus driver from drivers/i2c, strip
out the reminants of the platform specific parts of the old
PCF8583 RTC code, and remove the old obsolete PCF8583 driver.
