Typically only one of the character error conditions is true at a time. And
even if multiple errors were present at the same time we'd only want to
count one error per character.
For each character track whether at least one of the monitored error
conditions is true. Then count the number of characters for which at least
one error condition occurred. And finally add that sum to the total numbers
of errors.
This results in a slightly better utilization.

When the link is explicitly disabled through the control interface reset
the error statistics counter.
There is usually little benefit to preserving until after the link has been
disabled. If software is interested in the values it can read them before
disabling the link. Having them reset makes the behavior consistent with
all other internal state of the jesd204 RX peripheral, which is reset when
the link is disabled.

* jesd204: Add RX error statistics
Added 32 bit error counter per lane, register 0x308 + lane*0x20
On the control part added register 0x244 for performing counter reset and counter mask
Bit 0 resets the counter when set to 1
Bit 8 masks the disparity errors, when set to 1
Bit 9 masks the not in table errors when set to 1
Bit 10 masks the unexpected k errors, when set to 1
Unexpected K errors are counted when a character other than k28 is detected. The counter doesn't add errors when in CGS phase
Incremented version number
All the file names must have the same name as its module. Change all the
files, which did not respect this rule.
Update all the make files and Tcl scripts.
