Problem:
Kernel RO data is too large, about 4.5mb on 32bit and 5.9mb on

Solution:
1, replace __FILE__ definition, using relative path instead of
absolute path. This can help to save about 50KB memory. For example:

[ Upstream commit 4d217a5adc ]
The newly added 'rodata_enabled' global variable is protected by
the wrong #ifdef, leading to a link error when CONFIG_DEBUG_SET_MODULE_RONX
is turned on:
kernel/module.o: In function `disable_ro_nx':
module.c:(.text.unlikely.disable_ro_nx+0x88): undefined reference to `rodata_enabled'
kernel/module.o: In function `module_disable_ro':

kernel/module.o: In function `module_enable_ro':

CONFIG_SET_MODULE_RONX does not exist, so use the correct one instead.

Use touchscreen_properties structure instead of implementing all
properties by our own. It allows us to reuse generic code for parsing
device-tree properties (which was implemented manually in the driver for
now). Additionally, it allows us to report events using generic
touchscreen_report_pos(), which automatically handles inverted and
swapped axes.
This fixes the issue with the custom code incorrectly handling case where
ts->inverted_x and ts->swapped_x_y were true, but ts->inverted_y was
false. Assuming we have 720x1280 touch panel, ts->abs_x_max == 1279 and
ts->abs_y_max == 719 (because we inverted that in goodix_read_config()).
Now let's assume that we received event from (0:0) position (in touch
panel original coordinates). In function goodix_ts_report_touch() we
calculate input_x as 1279, but after swapping input_y takes that value
(which is more that maximum 719 value reported during initialization).
Note that since touchscreen coordinates are 0-indexed, we now report
touchscreen range as (0:size-1).
Developed and tested on custom DT-based device with gt1151 touch
panel.

Support was added based on Goodix GitHub repo [1]. There are two major
differences between gt1151 and currently supported devices (gt9x):
* CONFIG_DATA register has 0x8050 address instead of 0x8047,
* config data checksum has 16-bit width instead of 8-bit.
Also update goodix_i2c_test() function, so it reads ID register (which
has the same address for all devices) instead of CONFIG_DATA (because
its address is known only after reading ID of the device).
