Exposes load_settings to UARTComponent class

[edwardtfn]

What does this implement/fix?

This will expose load_settings (introduced on #5909) to UARTComponent class and any component using that class. I'm changing this as I wanna Nextion component to be able to change it's baud rate on the communication with the display without the need to create temporary UART components to handle it.

I will take a look at that later.
Are you running under esp32 or esp8266?

[SeByDocKy]

ESP32 ...

[DrCoolzic]

Yes I confirm breaking change for no good reason. It is ok that you add these fonctions as virtuals but NOT pure virtuals.....

[DrCoolzic]

I will take a look at that later. Are you running under esp32 or esp8266?

ESP32 ...

I cant do anything now because i am on a Phone but i will make a temp fix for you

Wont show up with esp8266 because ifdef
