[baremetal] Allow MaaS timeouts to be set via IDF

[baremetal] Allow MaaS timeouts to be set via IDF

Bump Pharos git submodule to pick up support for MaaS timeout
parameterization, as well as new IDF for lf-pod2.

Drop arch-specific MaaS timeouts, as they are now configurable
on a per-POD basis.

Sample usage (via IDF):

idf:
  fuel:
    maas:
      # MaaS timeouts (in minutes)
      timeout_comissioning: 10
      timeout_deploying: 15
