Kumar Gala 4192254ef2 dts: nios2: Add interrupt controller support in dts
Added properties to support the core interrupt controller on the NIOS2
cpu cores and enable that support for the NS16550 UART.

We rename some compatibles so that the cpu core compatibles is unique.

Timo Teräs 6fd168e9a1 driver: uart: ns16550: convert to DT_INST_*
Change to code to use the automatically generated DT_INST_*
defines and remove the now unneeded configs and fixups.

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Ramakrishna Pallala 6320043669 qemu: nios2: Enable UART 16550 driver for QEMU
Enable UART 16550 driver for Nios-II QEMU platform.

Note: This PR is tested with patched version Qemu 3.0.0 which
adds support for altera_10m50_zephyr machine type.
