The hardcoded `CONFIG_MAX_INTERRUPTS` limit of 32 was a significant
limitation, preventing the system from booting on complex SoCs with a
large number of interrupt sources.
To address this, this commit introduces two key changes:
1. The `CONFIG_MAX_INTERRUPTS` limit is increased to 1024. This value
is a power of two that accommodates a wide range of current and
future hardware.
2. The underlying data structure for tracking interrupt status has been
refactored to use a `u32` bitmap. This ensures that managing the
larger interrupt space remains memory-efficient and performant.
This enhancement improves the overall hardware compatibility of hvisor.
