There is no real phy driver, so s3c-hsudc just pokes the registers
itself. Improve this a little by making it a platform data callback
like we do for gpios.

There is only one board using this driver, and it's unlikely
that another would be added, so this is a minimal workaround.

s3c24xx has a custom implementation of the inb/outb family of I/O
accessors, implementing both general register access and ISA I/O port
through a multiplexer.

As far as I can tell, the first case has never been needed, and certainly
is not used now, as drivers only use inb/outb to actually driver ISA or
PCI port I/O.

Similarly, the special ISA support is limited to a single machine, the
Simtec Electronics BAST (EB2410ITX) with its PC/104 expansion connector,
all other machines could simply use the generic implementation from
asm/io.h that expects a single memory-mapped address range for byte,
word and dword access. As no other machines besides BAST actually selects
CONFIG_ISA, this is likely not even necessary.

As a cleanup, remove support for the non-ISA access from the helpers,
and make the ISA access use the virtual address window that we use
elsewhere for PCI I/O ports. In configurations without the BAST machine,
this now falls back on the generic implementation from asm/io.h, but
the mach/io.h header is still relied on to include a number of other
header files implicitly.

Commit f6361c6b ("ARM: S3C24XX: remove separate restart code")

Similarly to commit f6361c6b ("ARM: S3C24XX: remove separate restart
code"), the platform watchdog reset code can be removed in favor of
a generic watchdog driver which already handles reset.

This allows removal of a bunch of machine code and fixes also W=1
compile warnings:

    arch/arm/plat-samsung/watchdog-reset.c:29:6: warning: no previous prototype for 'samsung_wdt_reset' [-Wmissing-prototypes]

    arch/arm/plat-samsung/watchdog-reset.c:89:13: warning: no previous prototype for 'samsung_wdt_reset_init' [-Wmissing-prototypes]

The generic watchdog-based system reset is not exactly the same as
before.  The previous method had a fallback to soft_restart() which now
is gone.

The commit also removes a FIXME note about calling s3c64xx_clk_init()
inside s3c64xx_init_irq().  No one fixed this since long time and the
note is not meaningful anymore because watchdog part is removed.

A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not
really needed and the s3c24xx watchdog driver can depend on Samsung ARM
architectures instead.

The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung
platforms are here exceptions.  All others just depend on
CONFIG_ARCH_xxx.

This makes the code slightly smaller without any change in
