armv7m: Do not ignore 'value' parameter in armv7m_write_core_reg

Ignoring the value parameter in that function makes its code rather
misleading. Also the only caller of it, armv7m_restore_context already
does the whole "buf_get_u32" conversion business, so using
'value' also removes the waste of doing the conversion twice.
