Subject: [PATCH v2] char/tpm: Use true and false for bools

Bool initializations should use true and false.  Bool tests don't need
comparisons.  Based on contributions from Joe Perches, Rusty Russell
and Bruce W Allan.

The semantic patch that makes this output is available
in scripts/coccinelle/misc/boolinit.cocci.

More information about semantic patching is available at
http://coccinelle.lip6.fr/

v2:
Removed/changed that silly itpm = (probe == 0) ? 0 : 1; 
since probe is here either 0 or 1 -- thanks Al for noticing.
This section and the probing of the itpm can probably be improved anyway,
but I'll wrap that in a different patch soon.
