lib: utils/irqchip: always parse msi information for each aplic device

OpenSBI only parses MSI information of the first next level subdomain
for now, which makes the root domain misconfigured in some case:
1. the msi is not enabled on the first subdomain of the root domain,
   but other subdomains enable MSI.
2. the root domain is set as direct mode, but its subdomains enable MSI.

So it is needed to parse all child of the root domain, Otherwise, the
some non-root domains are broken. As the specification says, it is
safe to parse the MSI information of all its subdomain and write the
msiaddrcfg register of the non root domain as they are read only.

Parse the aplic MSI information recursively for all aplic device.
