This adds support for the GPIO IP "UPG GIO" used on
Broadcom STB SoCs (BCM7XXX and some others). Uses
basic_mmio_gpio to instantiate a gpio_chip for each bank.
The driver assumes that it handles the base set of GPIOs
on the system and that it can start its numbering sequence
from 0, so any GPIO expanders used with it must dynamically
assign GPIO numbers after this driver has finished
registering its GPIOs.

Does not implement the interrupt-controller portion yet,
will be done in a future commit.

v2:
- change include to use <linux/gpio/driver.h> instead of
  <linux/gpio.h>
- get rid of unnecessary imask member in struct bank
- rename GPIO_PER_BANK -> MAX_GPIO_PER_BANK
- always have 32 GPIOs per bank and add 'width' member in
  struct bank to hold actual number of GPIOs in use
- mark of_match table as const

Adds a new driver for Altera soft GPIO IP. The driver is able to do
read/write and allows GPIO to be a interrupt controller.

Tested on Altera GHRD on interrupt handling and IO.

v10:
- Updated conflicting device tree parameters
- Removed unused headers
- Used macro instead of magic numbers for ngpio
- Code readability cleanup using ?: and temporal variables
- Removed leftover garbage and unnecessary function calls
- Checked bgpio_init but unusable because Altera GPIO may not
  be a multiple of 8 bits

v9:
- Removed duplicated initialization on set_type using temporals
  to improve code readability in calling generic_handle_irq
- Using ?: ternary to reduce code size

v8:
- Using for_each_set_bit
- Added const for struct definition
- Removed naggy pr_err
- Sort alpha header
- Remove unused macros
- Use fixed width data types instead of unsigned long
- Whitespace issue fixes
- Removed _relaxed function for better compatibility across different
  CPU
- Changed irq_create_mapping to platform_get_irq updated implementation
  to use gpiochip_irqchip_add
- Reserve interrupt-cells number 2 in device tree binding for future
  use
- Remove confusing sections on devicetree bindings
- Added tristate Kconfig help text

v7:
- Used dev_warn instead of pr_warn
- Clean up unnecesarry if else indentation

v6:
- Added irq_startup and irq_shutdown
- Changed bitwise clamping style
- Cleanup bitwise operation to improve readability change naming of
  mapped irqs from virq to mapped_irq

v5:
- Dispose irq_domain mapping correctly
- Update optional binding description in binding docs

v4:
- Added vendor prefix to devicetree binding for IP specific properties
  using MMIO GPIO helper library instead of manually map PIO to memory
- altera_gpio_chip inline struct documentation to kerneldoc
- Using dev_ print to print a better failure message

v2, v3:
- Do not reference NO_IRQ
- Updated irq_set_type to only allow the hardware configured irq type
