Added a flash driver for the STM32G4 series. The primary change here is
the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash
driver as a template. The primary difference is the accounting for dual
banks with different page sizes.
Fixed error while building b-g474e-dpow1/buckboost. It was possible (technically) to have page be used uninitialzied. Changing the if statement to default to using a flash_page_size == 2048 fixes this issue.
In armv8m the FPSCR[18:16] LTPSIZE field must be set to 0b100 for
"Tail predication not applied" as it's reset value.

Add _dl_find_object() function, because when cxx_exception configuration is enabled, a link error occurs and that function cannot be found.

We save interrupted TCB state on tcb->xcp.regs not interrupt stack now
which allows us to remove x86_64_savestate() from up_switch_context()
and other places.

1. The -c parameter should not be added during the link phase, otherwise the link will fail.
2. If it is the clang compiler, its toolchain library should use --print-file-name to find it, otherwise an error will occur

When neon is enabled, compiler may optimize 64bits access to vstr, that
will cause data aborts.
Split 64bits access to double 32bits access for GIC_IROUTER/GICR_TYPER,
just like linux.

Need to save the regs firstly in case syslog triggers another crash.
Otherwise we may loose the register contents for the first exception.
