The geni_se_clk_freq_match() has some strange semantics. Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then
...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.
The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way. ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

The function clk_round_rate() is defined to return a "long", not an
"unsigned long". That's because it might return a negative error
code. Change the call in geni_se_clk_tbl_get() to check for errors.
While we're at it, get rid of a useless init of "freq".
NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable. Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

This patch contains several small cleanups:
- In qcom_smem_enumerate_partitions(), change the "local_host"
argument to have 16 bit unsigned type
- Also in qcom_smem_enumerate_partitions(), change the type of
the "host0" and "host1" local variables to be u16
- Fix error messages reporting host ids to use the right format
specifier
- Shorten the error messages as well, to fit on one line
- Add a compile-time check to ensure the local host value passed
to qcom_smem_enumerate_partitions() is in range

In qcom_smem_enumerate_partitions(), we find all partitions that
have a given local host id in either its host0 or its host1 field
in the partition table entry. We then verify that the header
structure at the start of each partition also contains the same two
host ids as is found in the table of contents.
There is no requirement that the order of the two host ids be the
same in the table of contents and in the partition header.
This patch changes that, requiring host0 to in the partition table
entry to equal host0 in the partition header structure (and similar
for the host1 values).

In qcom_smem_set_global_partition(), we check whether the header

so the partition header must have SMEM_GLOBAL_HOST for *both* its

In qcom_smem_enumerate_partitions(), any partition table entry
having a zero offset or size field is ignored. Move those checks
earlier in the loop, because there's no sense in examining the
host fields for those entries.
Add the same checks in qcom_smem_set_global_partition(), so the
scan for the global partition skips over these invalid entries.
This allows a later check for zero size or offset once the global
entry is found to be eliminated.
