[PATCH] tpm: new 1.2 sysfs files
Many of the sysfs files were calling the TPM_GetCapability command with array.
Since for 1.2 more sysfs files of this type are coming I am generalizing the
array so there can be one array and the unique parts can be filled in just
before the command is called.
This updated version of the patch breaks the multi-value sysfs file into
separate files pointed out by Greg. It also addresses the code redundancy and
ugliness in the tpm_show_* functions pointed out on another patch by Dave
Hansen.
