[sw] Revamp api's to suoport CHERI

On a CHERI target it's not possible to blindly convert a physical address
to a pointer; change relevant api's to take one or more base addresses
instead. Note this intentionally does not save the base addresses in
static variables or similar; we pass the necessary pointers to each call
to (potentially) avoid memory references.

NB: rention_sram_get is retained for non-cheri targets to mimimize churn;
this should be removed if/when api's are updated as described above.

Specific changes:
- otp_* take a base address
- sec_mmio_* take a uintptr_t instead of a uint32_t
- device_fpga_Version_print takes a uintptr_t
- bootstrap_* take uintptr_t's
- boot_data_* take uintptr_t's
- alert_* take uintptr_t's
- ast_* take unitptr_t's
- flash_ctrl* take unitptr_t's
- ibex_* take uintptr_t's
- otbn_* take unitptr_t's
- pinmux_* take unitptr_t's
- retention_sram_* take uintptr_t's
- rnd_* take uintptr_t's
- spi_device_* take uintptr_t's
- watchdog_* take uintptr_t's
- shutdown_* take uintptr'ts
- sigverify_* take uintptr'ts

TODO(shutdown): SHUTDOWN_IF_ERROR is broken

Bypass-Presubmit-Reason: verified as part of topic

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
