[ Upstream commit 4881873f4cc1460f63d85fa81363d56be328ccdc ]

According to the public S805 datasheet the RESET2 register uses the
following bits for the PIC_DC, PSC and NAND reset lines:
- PIC_DC is at bit 3 (meaning: RESET_VD_RMEM + 3)
- PSC is at bit 4 (meaning: RESET_VD_RMEM + 4)
- NAND is at bit 5 (meaning: RESET_VD_RMEM + 4)

Update the reset IDs of these three reset lines so they don't conflict
with PIC_DC and map to the actual hardware reset lines.

[ Upstream commit 1c226017d3ec93547b58082bdf778d9db7401c95 ]

Current USB3503 driver ignores GPIO polarity and always operates as if the
GPIO lines were flagged as ACTIVE_HIGH. Fix the polarity for the existing
USB3503 chip applications to match the chip specification and common
convention for naming the pins. The only pin, which has to be ACTIVE_LOW
is the reset pin. The remaining are ACTIVE_HIGH. This change allows later
to fix the USB3503 driver to properly use generic GPIO bindings and read
polarity from DT.

[ Upstream commit e17e7c498d4f734df93c300441e100818ed58168 ]

On am57xx-beagle-x15, 5V0 is connected to P16, P17, P18 and P19
connectors. On am57xx-evm, 5V0 regulator is used to get 3V6 regulator
which is connected to the COMQ port. Model 5V0 regulator here in order
for it to be used in am57xx-evm to model 3V6 regulator.
