This patch includes initial support for FT800 display driver.
It includes basic features. It can be easily extended with more
FT800 display list and co-processor features.

STATUS32.DZ(bit 13) is the EV_DivZero exception enable bit, and it's
not enabled by default. we need to set it explicitly to enable divide
zero exception on early boot and each thread's setup.
The DZ bit is ignored on write and read as zero when there is no
hardware division configured. So we can simply set DZ bit even if
there is no hardware division configured.

This feature predated the tickless kernel and has been in legacy mode
for a while. We now have no drivers or systems that do not support
tickless, so remove this option and cleanup the code to only use
tickless.

The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers
and add support for new hardware and are documented and available to be
used outside of the clock/kernel subsystems.
Remove the leading z_ and provide them as clock_* APIs for someone
writing a new timer driver to use.

Prefix internal functions and structs with modbus_.
Use unit_id consistently instead of node_addr.
Fix mbm_ remainder and rename to mbc_.
Rename struct modbus_frame to modbus_adu since
ADU is closer to what the structure represents.

remove ifdef around mbc_validate_fc03fp_response().

We need to do a few things differently if we are to support
a virtual memory map, i.e. CONFIG_MMU where CONFIG_KERNEL_VM_BASE
is not the same as CONFIG_SRAM_BASE_ADDRESS.
- All sections must be specified with a VMA and LMA, where
VMA is the virtual address and LMA is the physical memory
location.
- All sections must be specified with ALIGN_WITH_INPUT to
keep VMAs and LMAs synchronized
To do this, the existing linker macros need some adjustment:
- GROUP_LINK_IN undefined when CONFIG_KERNEL_VM_BASE is not
the same as CONFIG_SRAM_BASE_ADDRESS.
- New macro GROUP_ROM_LINK_IN for text/rodata sections
- New macro GROUP_NOLOAD_LINK_IN for bss/noinit sections
- Implicit ALIGN_WITH_INPUT for all sections
GROUP_FOLLOWS_AT is unused anywhere in the kernel for years
now and has been removed.

Switch to the new API for delayed work related to DNS queries.
In the previous solution it was assumed that the work item could be
immediately cancelled at the point the query slot was released. This
is not true. We need a secondary condition to record the fact that
the query was completed while the work item was still pending, and an
additional check to detect when the work item completed and the slot
reclaimed.
Also annotate functions to indicate when they require the lock on
query content to be held, add some helpers that abstract core
operations like invoking a callback or releasing a query slot, and fix
some more cases where query slot content was accessed outside of the
new lock infrastructure.
