tpm, tpm_tis: correct tpm_tis_flags enumeration values

Browse source 
commit 4ecd704a4c51fd95973fcc3a60444e0e24eb9439 upstream.

With commit 858e8b792d06 ("tpm, tpm_tis: Avoid cache incoherency in test
for interrupts") bit accessor functions are used to access flags in
tpm_tis_data->flags.

However these functions expect bit numbers, while the flags are defined
as bit masks in enum tpm_tis_flag.

Fix this inconsistency by using numbers instead of masks also for the
flags in the enum.
