gpio: add new functions to set/get pin/port values

Browse source 
This commit adds following functions which work with pin logical levels
(take into account GPIO_ACTIVE_LOW flag):
- gpio_port_get, gpio_port_set_masked, gpio_port_set_bits,
  gpio_port_clear_bits, gpio_port_set_clr_bits
- gpio_pin_get, gpio_pin_set
Functions which work with pin physical levels:
- gpio_port_get_raw, gpio_port_set_masked_raw, gpio_port_set_bits_raw,
  gpio_port_clear_bits_raw, gpio_port_set_clr_bits_raw
- gpio_pin_get_raw, gpio_pin_set_raw
As well as functions:
- gpio_port_toggle_bits, gpio_pin_toggle_bits
