regulator: core: update two debug messages

1)
In print_constraints_debug(), the power budget is printed as:

   lldo2: 450 <--> 1300 mV at 900 mV 2147483647 mW budge, enabled

(note the missing t in budget). This is because there is a --count just
below the call to scnprintf(), to make space for the comma. All similar
calls to scnprintf() above add an extra space to the format string to
allow for that, but this one doesn't, so the last character t is
stripped instead. Update the format string to fix the message.

2)
Add the name of the supply to the failure message printed when the
supply can not be resolved when debug messages are enabled to help with
debug.
