- Change spin_lock + local_irq_save into spin_lock_irqsave
- Change spin_unlock + local_irq_restore into spin_unlock_irqrestore
- Return ENOTTY if ioctl is not recognized as a cris ioctl.
- Make init functions static.

Changes as suggested by Andrew Morton, plus general cleanup to
ease later consolidation of driver into machine common driver.

- Correct parameter type of gpio_write to const char __user *
- Remove volatile from the arrays of machine dependent registers, use
  readl and writel to access them instead.
- Remove useless casts of void.
- Use spin_lock_irqsave for locking.
- Break gpio_write into smaller sub-functions.
- Remove useless breaks after returns.
- Don't perform any change in IO_CFG_WRITE_MODE if values are invalid.
  (previously values were set and then set to zero)
- Change cast for copy_to_user to (void __user *)
- Make file_operations gpio_fops static and const.
- Make setget_output static. (However, it's still inline since the CRIS
  architecture is still not SMP, which makes the function small enough
  to inline)

Clean up issues noticed by Andrew Morton:

- Use a combined struct for allocating the mtd_info and nand_chip structs
  instead of using anonymous memory as the example in
  Documentation/DocBook/mtdnand.tmpl
- Use kzalloc instead of using kmalloc/memset(0)
- Make crisv32_device_ready static.

- Change parameters of gpio_write (const char * buf -> const char __user *buf)
- Don't initialize static variables to zero.
- Remove useless casts from void.
- Change name of interrupt routine (gpio_pa_interrupt -> gpio_interrupt)
- Use kzmalloc instead of allocating memory and zeroing it manually.
- Correct casts for copy_to_user and copy_from_user to (void __user *)
- Make file_operations gpio_fops static.
- Make ioif_watcher static, not used outside this file.

- Add ifdef around macros to read and write hardware registers
- Add parens around REG_READ expression to avoid possible precedence errors.
- Remove useless CVS id tag.

This file is machine dependent, and needs to be in
asm-cris/arch-v32/mach-fs/hwregs/reg_map.h instead.

CRIS v32 is not SMP.

Deallocation was not possible before, but is now.

Also, fix a typo.

- A couple of fields have changed name:
reg_eth_rw_ga_lo.table -> tbl
reg_eth_rw_ga_hi.table -> tbl
reg_eth_rw_gen_ctrl.flow_ctrl_dis -> flow_ctrl

- Add some new register fields.
reg_eth_rw_gen_ctrl.gtxclk_out
reg_eth_rw_gen_ctrl.phyrst_n
reg_eth_rw_tr_ctrl.carrier_ext

- max_size in reg_eth_rw_rec_ctrl had the wrong size.

- Registers reg_eth_rw_mgm_ctrl and reg_eth_r_stat was reworked completely.

The old name "r" would quite often produce warnings when other
variables with the same name was shadowed. Rename it __x to
make it more unlikely to happen.

Both of these are implemented using cris_delay10ns().

This is done to avoid collision with linux/leds.h

Also, clean up some whitespace errors.

Also, fix some white space errors, and constify cpuinfo_op.
