ISO 8601 defines 'T' as a separator between date and time. Though,
some ABIs use time and date with ' ' (space) separator instead.

Add a flavour to the %pt specifier to override default separator.

Use %ptTs instead of open coded variant to print contents
of time64_t type in human readable form.

Use sysfs_emit() at the same time in the changed functions.

Any clue what route this will take into the kernel? I'm certainly happy
for someone else to take the kdb bits alongside the vsprintf stuff
(so here's an acked-by too in case they are fussy about that sort of
thing ;-) ):

I am going to queue the entire patchset for 5.14 via the printk tree
the following week unless anyone complains in the meantime.
