device-nokia-n900: block non-critical modules (MR 4227)

* modem-related modules seem partly responsible for recent l3 firewall
     timeouts and kernel crashes.
 * rx51-battery can be used to get battery design capacity, but not required
    for general running of the system blacklist other
 * modules that can impact power consumption on the N900

Completely disabling the modules in kernel config is unnecessary, since they
are all useful for some users
