tpm: i2c: atmel: fix block comment formatting 



Multiple block comments in tpm_i2c_atmel.c placed the closing '*/' on the
same line as the comment text. This violates the kernel's preferred
comment style, which requires the closing delimiter to appear on its
line.

Fix the formatting to improve readability and resolve checkpatch
warnings.
