st7789v for 240x320 screen IPS?

**Describe the problem you have/What new integration you would like**

the st7789v is design for TTgo screen only...135x240
**Please describe your use case for this integration and alternatives you've tried:**

i try to use the st7789v custom_component from @musk95 but even if i have put 240 and 320 instead of 135 and 240 in the "st7789v.cpp" line 265 and 269 but it boot loop.
**Additional context**

the screen IPS 2.0" is cheap and very bright and clear...so sad that the standard 240x320 pixel is not (yet) supported by the st7789v driver in EspHome...

Start by examining the st7789v.cpp references at lines 265 and 269 and compare the custom component's handling of 135x240 with the requested 240x320 dimensions. Reproduce the boot loop with the 2.0-inch IPS screen, then verify that a 240x320 configuration boots and displays correctly.
