The recv variable in sandbox_tpm2_fill_buf() is a pointer on a pointer
of a char array. It means accessing *recv is the char array pointer
itself while **recv is the first character of that array. There is no
need for such indirection here, so simplify the code.

Simplifying things will make the last assignment right: "*recv = NULL"
is now correct. The issue has been found by the following Coverity
Scan report:

    CID 183371:  Incorrect expression  (UNUSED_VALUE)
    Assigning value "4UL" to "*recv" here, but that stored value is overwritten before it can be used.
    232             *recv += sizeof(rc);
    233
    234             /* Add trailing \0 */
    235             *recv = NULL;

While at simplifying things, use '\0' instead of NULL when adding an
empty char at the end of the buffer.

The second check on pcr_map in sandbox_tpm2_xfer() is wrong. It should
check for pcr_map not being empty. Instead, it is a pure copy/paste of
the first check which is redundant.

This has been found thanks to a Coverity Scan report:

    CID 183370:  Memory - illegal accesses  (UNINIT)
    Using uninitialized value "pcr_index".
        put_unaligned_be32(tpm->pcr_extensions[pcr_index], recv);

This is because pcr_index is initialized only if the user input is
correct, ie. at least one valid bit is set in pcr_map.

Fix the second check and also initialize pcr_index to 0 (which is
harmless in case of error) to make Coverity Scan happy.

In case the slow clock is not properly configured, the UTMI clock
cannot lock the PLL, because UPLLCOUNT will "wait X slow clock cycles".
In this case U-boot will loop indefinitely.
Added a timeout in this case, to start U-boot even if UTMI clock is
not enabled, so the user can use different media if needed, or investigate.
