adiv6: use struct adiv5_ap->ap_num to contain the AP base address

Browse Source 
ADIv5 DAP can only have 256 AP, while ADIv6 can provide till
2**40 (1,099,511,627,776) AP per DAP.

Reuse the field ap_num in struct adiv5_ap, currently used on ADIv5
to hold the ADIv5 AP number (apsel), to contain the ADIv6 AP base
address.

Convert struct adiv5_ap->ap_num to 64 bit and initialize it to
DP_APSEL_INVALID for unused AP.
Restrict dap_find_get_ap() to ADIv5 only. To be enhanced.
On ADIv6, let dap_get_ap() return an already allocated AP, or
allocate and return an unused AP.
Add function is_ap_num_valid() and use it.
