State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

The angle observer always refer to a motor electrical angle,
while the speed observer can be applied to a motor electrical speed or a motor mechanical speed.
They can be used completely independently, so they should'n be coupled.
For example, a sensored motor controller in speed control mode doesn't need an angle estimator.
The packed-attribute on the tcb_info_s type was misplaced, which caused
incompatible memory layout between host and target. According to
current GCC documentation:
> You may specify type attributes in an enum, struct or union type
> declaration or definition by placing them immediately after the struct,
> union or enum keyword. You can also place them just past the closing
> curly brace of the definition, but this is less preferred because
> logically the type should be fully defined at the closing brace.
I also added jlink-nuttx.so to the .gitignore list and updated nxstyle
to ignore the camel case function names required by JLinkGDBServer.

Add a list in TCB to track all semphores the task held, so we
can release all holders when exit, so nxsched_verify_tcb
is unnecessary.

Basically, mirror the following two commits from modlib.
It's shame we have two copies of elf loaders.

modlib: Implement sh_addralign handling
I've seen a module with 16 bytes .rodata alignment for xmm operations.
It was getting SEGV on sim/Linux because of the alignment issue.
The same module binary seems working fine after applying this patch.
Also, tested on sim/macOS and esp32 on qemu,
using a module with an artificially large alignment. (64 bytes)

modlib: Always use separate allocation for text and data
Pros:
* Reduce code differences
* Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT
Cons:
* Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total
Tested with:
* sim:module on macOS
* esp32-devkit:nsh + CONFIG_MODULE on qemu
* lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu

Some PPG devices have 4 ADCs to output quad-channel PPG values while some of them only have 2 ADCs to output dual-channel PPG.
To deal the case above, the type PPGD(PPG of Dual-channel) takes the place of former type PPG, which also have 2-channel PPG outputs. Type PPGQ (PPG of Quad-channel) is new for 4-ADC-PPG. Both types have contained new data "gain" to indicate ADC gains of each PPG channel, for the reason that the gains may vary during automatical optical adjustments.
