bootloader: bl_boot: Fix disabling of UARTs

This is a follow-up to commit 56d117d
("bootloader: bl_boot: update UART Kconfigs").

- add missing `CONFIG_` prefixes to `HAS_HW_NRF_*` symbols
- remove invalid entries that refer to non-existing peripherals
  (UART1 and UART2)
- move `#ifdef CONFIG_UART_NRFX` to the function, where it is actually
  needed (`CONFIG_UART_NRFX_UART` and `CONFIG_UART_NRFX_UARTE` imply
  `CONFIG_UART_NRFX`, as they cannot be defined otherwise, so there is
  no need for that additional `#ifdef` in inclusions).
