f3af6edf93 Kconfig: add quotes in source to clean warnings from setconfig

0a4982a80e Introduce ARCH_HAVE_EXTRA_HEAPS, this config is going to be used for 
chips that have multiple separate heaps.
For now it's used to enable APIs to initialize the different heaps
during the start sequence but can be extended for other purposes that
manage those heaps.

08c4376606 arch, include, sched : Refactor ARCH_GLOBAL_IRQDISABLE related code 
Summary:
- ARCH_GLOBAL_IRQDISABLE was initially introduced for LC823450 SMP
- At that time, i.MX6 (quad Cortex-A9) did not use this config
- However, this option is now used for all CPUs which support SMP
- So it's good timing for refactoring the code

Impact:
- Should have no impact because the logic is the same for SMP

Testing:
- Tested with board: spresense:smp, spresense:wifi_smp
- Tested with qemu: esp32-core:smp, maix-bit:smp, sabre-6quad:smp
- Build only: lc823450-xgevk:rndis, sam4cmp-db:nsh

545cfada38 This commit removes CONFIG_ARCH_INT_DISABLEALL. In the normal course of things, interrupts must occasionally be disabled using the up_irq_save() inline function to prevent contention in use of resources that may be shared between interrupt level and non-interrupt level logic. Now the question arises, if we are using BASEPRI to disable interrupts and have high priority interrupts enabled (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except SVCall (we cannot disable SVCall interrupts). Or do we only disable the "normal" interrupts? 
If we are using the BASEPRI register to disable interrupts, then the answer is that we must disable ONLY the "normal interrupts".  That is because we cannot disable SVCALL interrupts and we cannot permit SVCAll interrupts running at a higher priority than the high priority interrupts (otherwise, they will introduce jitter in the high priority interrupt response time.)

Hence, if you need to disable the high priority interrupt, you will have to disable the interrupt either at the peripheral that generates the interrupt or at the NVIC.  Disabling global interrupts via the BASEPRI register cannot effect high priority interrupts.
