Move minidump specific data types and macros to a separate internal
header(qcom_minidump.h) so that it can be shared among different
minidump.h should be good as we are already in include/soc/qcom/
Initially, i wanted to protect the content of qcom_minidump.h between
qcom_minidump.c and qcom_common.c
Ideally, here qcom_minidump.h should be supplier/provider header and can
be shared among above qcom_minidump.c and qcom_common.c but since they
are not in same directory, moved it inside include/soc/qcom/ as separate
header than consumer header minidump.h .

Qualcomm drivers.
There is no change in functional behavior after this.
