drivers: stm32_gpio: add helper function stm32_gpio_get_bank()

Adds helper function stm32_gpio_get_bank() in stm32_gpio to retrieve
a GPIO bank instance from the bank ID. This change will allow a later
change to remove now useless platform helper functions
stm32_get_gpio_bank_base() and stm32_get_gpio_bank_clk().

This changes removes the verification of GPIO banks clock reference
against platform data (in ckeck_gpio_bank()) which is not really useful
as we can consider embedded DTB data are reliable.

Checks clk_enable() return value to panic on failure.

core: define main interrupt controller data from its driver

All but one platforms define CPU core interrupt controller from their
platform main.c source file next to its main interrupt handler.
This change factorize these implementation by moving the definition
of the controller data instance straight in the controller driver
source file. This change makes each controller driver to implement
straight itr_core_handler() function, preventing a extra branch on
interrupt execution. Interrupt controller driver initialization
function now straight calls itr_core_init().

This changes treats case when CFG_CORE_WORKAROUND_ARM_NMFI is enable
to not conflict with core/arch/arm/kernel/thread.c that already
overrides itr_core_handler() weak implementation.

With this change, the main controller initialization function
(gic_init(), gic_init_base_addr(), gic_cpu_init() and hfic_init())
no more gets the controller data as input argument.

As a consequence, definition of struct hfic_data and struct gic_data
moves from their respective driver header file to the respective
driver source file.

As a consequence, gic_dump() no more requires an argument.
