dt-bindings: ata: ahci: Add platform capability properties

In case if the platform doesn't have BIOS or a comprehensive firmware
installed then the HBA capability flags will be left uninitialized. As a
good alternative we suggest to define the DT-properties with the AHCI
platform capabilities describing all the HW-init flags of the
corresponding capability register. Luckily there aren't too many of them.
SSS - Staggered Spin-up support and MPS - Mechanical Presence Switch
support determine the corresponding feature availability for the whole HBA
by means of the "hba-cap" property. Each port can have the "hba-port-cap"
property initialized indicating that the port supports some of the next
functionalities: HPCP - HotPlug capable port, MPSP - Mechanical Presence
Switch attached to a port, CPD - Cold Plug detection, ESP - External SATA
Port (eSATA), FBSCP - FIS-based switching capable port.

dt-bindings: ata: ahci-platform: Clarify common AHCI props constraints

Indeed in accordance with what is implemented in the AHCI platform driver
and the way the AHCI DT nodes are defined in the DT files we can add the
next AHCI DT properties constraints: AHCI CSR ID is fixed to 'ahci', PHY
name is fixed to 'sata-phy', AHCI controller can't have more than 32 ports
by design, AHCI controller can have up to 32 IRQ lines.

dt-bindings: ata: ahci-platform: Detach common AHCI bindings

In order to create a more sophisticated AHCI controller DT bindings let's
divide the already available generic AHCI platform YAML schema into the
platform part and a set of the common AHCI properties. The former part
will be used to evaluate the AHCI DT nodes mainly compatible with the
generic AHCI controller while the later schema will be used for more
thorough AHCI DT nodes description. For instance such YAML schemas design
will be useful for our DW AHCI SATA controller derivative with four clock
sources, two reset lines, one system controller reference and specific
max Rx/Tx DMA xfers size constraints.

Note the phys and target-supply property requirement is preserved in the
generic AHCI platform bindings because some platforms can lack of the
explicitly specified PHYs or target device power regulators.

Also note the SATA/AHCI ports properties have been moved to the
$defs-paragraph of the schemas. It's done in order to create the
extendable properties hierarchy such that particular AHCI-controller
could add vendor-specific port properties.
